SGM6021  
400nA Ultra-Low Power, Buck Converter  
with 200mA Output Current  
GENERAL DESCRIPTION  
FEATURES  
The SGM6021 family is a 200mA, 1.4MHz synchronous  
Buck DC/DC converter with 400nA ultra-low quiescent  
current, which is ideal for powering ultra-low power  
applications with special needs.  
Input Voltage Range: 1.8V to 5.5V  
Output Voltage Programmable in Operation  
High Efficiency at Low Output Currents:  
Up to 90% with IOUT = 0.1mA  
Ultra-Low Power Buck Converter  
200mA (MAX) Output Current  
The SGM6021 operation voltage range is from 1.8V to  
5.5V, allowing the use of a regulated 5V input. The  
output regulator levels are programmed through VS pin  
and can be programmed for 4 different voltages,  
making it ideal for designing device with limited power  
budget calculation.  
400nA (TYP) Quiescent Current  
100% Duty Cycle (Pass Mode)  
-40to +85Operating Temperature Range  
Available in a Green UTDFN-1.5×2-6L Package  
The SGM6021 delivers an output current of 200mA with  
a peak inductor current of 430mA. Besides, the  
SGM6021 series has the under-voltage lockout (UVLO)  
function. It is disabled when the voltage on VIN reaches  
the UVLO condition. The SGM6021’s under-voltage  
lockout level is continuously monitored. Only inductor,  
CIN and COUT capacitors are needed as external  
components to make a Buck DC/DC converter solution.

ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.

DETAILED DESCRIPTION  
The SGM6021 family is a synchronous Buck converter  
with ultra-low quiescent current of 400nA (TYP). The  
device is improved to provide high efficiency ranging  
from 10μA to 200mA. The SGM6021 family equips an  
externally regulated supply that is programmable. Thus,  
the power-management stage efficiency is maintained.  
average output current of 200mA with a peak inductor  
current of 430mA (TYP). The device implements an  
input under-voltage lockout (UVLO) function. When the  
input voltage drops below the UVLO threshold, the  
device stops operation. In addition to input UVLO  
function, the SGM6021 also implements the VS pin to  
allow external signal to control the turn-on and turn-off  
of the device. The device also implements output  
discharge function, when the VS pin is pulled to logic  
low, the low-side power FET remains on to discharge  
the output voltage. The SGM6021 also implements 100%  
duty cycle mode to bypass the input voltage to the  
output when the input voltage is above the UVLO  
threshold.  
The SGM6021 implements the hysteretic control  
architecture to regulate the output voltage. The 400nA  
(TYP) quiescent current extends the operation lifetime  
for battery operated applications.  
Operation  
The SGM6021 family is a Buck converter that is  
capable to regulate the voltage that is lower than the  
input voltage at the output. The device implements the  
pulse frequency modulation (PFM) control to regulate  
the voltage at light load. The SGM6021 delivers an

DETAILED DESCRIPTION (continued)  
After that, the pulses at VS pin become effective and  
can be used to shut down the IC or program the output  
voltage. The following are the three cases that the VS  
pin affects the regulator:  
Effective Pulse at VS Pin  
A pulse with width less than tPULSE is treated as an  
effective pulse. Consecutive pulses will be counted if  
delay between adjacent pulses is within the tSTOP  
Please refer to Figure 3 for a graphical explanation.  
.
1. 1 pulse followed by VS pin being low for longer than  
tOFF will shut down the regulator.  
3ms < tPULSE <6ms  
During the tOFF-HOLD time after shutdown, the pulses  
applied to VS Pin are ignored.  
3ms < tPULSE <6ms  
To restart the regulator, the VS pin must be pulled high  
for at least tSS time.  
Figure 3. Effective Pulse at VS Pin  
2. 2~5 pulses followed by VS pin being high for longer  
than tOFF will set the output voltage to the default, V1,  
V2 and V3 respectively.  
VS Pin Interface Functions  
In order to enable the IC from shutdown mode, two  
conditions must be met:  
3. 2 or more pulses followed by VS pin being low for  
longer than tOFF will set the output voltage to the default  
value.  
1. VIN voltage is higher than UVLO threshold.  
2. VS pin is floating or VS pin stays logic high for at  
least tBLANK + tSS time.  
Other pulse patterns will have no effects on the IC.  
1 pulse at VS

VS high for  
For startup from shutdown,  
5 pulses at VS pin after  
OFF-HOLD + tSS, and setting  
VS high for longer than  
STOP, output V3.  
4 pulses at VS pin and  
6 pulses at VS pin and  
setting VS high for  
longer than tSTOP, output

Setting VS low for longer than

the regulator will shut down.

Under-Voltage Lockout (UVLO)  
The device monitors the input voltage and shuts down  
itself when the input voltage is lower than UVLO  
threshold voltage. When the input voltage is higher  
than the UVLO threshold plus hysteresis, the device  
will start again.  
Nano-Power Management and Efficiency  
The SGM6021 implements the nano-power circuitry  
and algorithm to achieve 400nA (TYP) quiescent  
current. This feature is accomplished through sampling  
and all references are saved, so as to lower the  
average quiescent current. During the sampling and  
saving, the internal circuits are only turned on for a  
short period of time and then turned off in the remaining  
time at the lowest feasible duty cycle.  
Thermal Shutdown (TSD)  
A thermal shutdown function is implemented to prevent  
the damage caused by excessive heat and power  
dissipation. Once a temperature of +160°C (TYP) is  
exceeded, the device is shut down. The device is

400nA Ultra-Low Power, Buck Converter  
with 200mA Output Current  
SGM6021  
APPLICATION INFORMATION  
The SGM6021 family has ultra-low quiescent current  
and is capable of delivering up to 200mA load current,  
which is suitable for battery operated applications.  
the amount of output voltage drop during load step.  
Inductor Selection  
The SGM6021 is optimized to work with a 4.7μH  
inductor. The selected inductor’s saturation current  
should be at least 25% higher than the maximum  
cycle-by-cycle current limit specified in the Electrical  
Characteristics table. The SGM6021 is naturally stable  
due to its hysteretic control architecture.  
Design Procedure  
A 10μH inductor (Toko DFE2520- 12C) and a 22μF  
input ceramic capacitor are recommended for the  
SGM6021. Since the device only supports 200mA  
output load, a 22μF output ceramic capacitor is  
sufficient. For applications that are expected to have a  
large transient event, use ITRAN = COUT × ΔVOUTTIME to  
size the output capacitor accordingly, where ΔVOUT is  
The recommended inductors for SGM6021 are shown  
in Table 1.

Output Capacitor Selection  
Input Capacitor Selection  
A minimal of 22μF ceramic output capacitor is  
recommended for SGM6021. Larger size will result in  
higher effective capacitance under the same DC  
de-rating, which improves the transient response and  
output ripple.  
A 22μF ceramic capacitor and a 0.1μF ceramic bypass  
input capacitor are recommended to place between the  
VIN pin and GND as close as possible to minimize the  
parasitic inductance. For applications where the  
SGM6021 is located far away from the input source, a  
22µF or higher capacitor is recommended to damp the  
inductance of the wiring harness.
