2. Description
The LXDC32D series is a low power step-down DC-DC converter suitable for space-limited or noise-sensitive
applications. The device utilizes an inductor-embedded ferrite substrate that reduces radiated EMI noise and
conduction noise.
By adding output capacitors, it can be used as an LDO replacement. Its low noise and easy-to-assemble features
assure reliable power supply quality.
The device works in PFM mode at light load for extended battery life. At heavy load, it changes to PMW mode
automatically and maintains high efficiency using synchronous rectifying technology.
The device provides good output voltage accuracy even in PFM mode. It maintains 2% DC voltage accuracy over
the full current range (0-600mA, depends on output voltage), and shows very smooth mode transition between
PFM mode and PWM mode.

Power Dissipation (mW)
The output current of the device may need to be de-rated if it is operated in a high ambient temperature or in a
continuous power delivering application. The amount of current de-rating is highly dependent on the
environmental thermal conditions, i.e. PCB design, nearby components or effective air flows. Care should
especially be taken in applications where the device temperature exceeds 85oC.

o
The IC temperature of the device must be kept lower than the maximum rating of 125 C. It is generally
recommended to take an appropriate de-rating to IC temperature for a reliable operation. A general de-rating for
the temperature of semiconductor is 80%.
MLCC capacitor’s reliability and the lifetime is also dependant on temperature and applied voltage stress. Higher
temperature and/or higher voltage cause shorter lifetime of MLCC, and the degradation can be described by the
Arrhenius model. The most critical parameter of the degradation is IR (Insulation Resistance). The below figure
shows MLCC’s B1 life based on a failure rate reaching 1%. It should be noted that wear-out mechanisms in
MLCC capacitor is not reversible but cumulative over time.

Capacitor Case temperature(
)
The following steps should be taken before the design fix of user’s set for reliable operation.
1. The ambient temperature of the device should be kept below 85 oC
2. The IC temperature should be measured on the worst condition of each application. The temperature must be
kept below 125 oC. An appropriate de-rating of temperature and/or output current should be taken.
3. The MLCC temperature should be measured on the worst condition of each application. Considering the above
figure, it should be checked if the expected B1 life of MLCC is acceptable or not.
7. Detailed Description
PFM/PWM Mode
If the load current decreases, the converter will enter PFM mode automatically. In PFM mode, the device operates
in discontinuous current mode with a sporadic switching pulse to keep high efficiency at light load.
The device uses constant on-time control in PFM operation, which produces a low ripple voltage and accurate
output voltage compared with other PFM architectures. Because of the architecture, DC output voltage can be
kept within +/-2% range of the nominal voltage and the output ripple voltage in PFM mode can be reduced by just
increasing the output capacitor.
The transition between PFM and PWM is also seamless and smooth.
The transition current between PFM and PWM is dependent on Vin, Vout and other factors, but the approximate
threshold is about 100-200mA.

PFM mode at light load
PWM mode at heavy load
Nominal output voltage
UVLO (Under Voltage Lock Out)
The input voltage (Vin) must reach or exceed the UVLO voltage (1.4Vtyp) before the device begins the start up
sequence even when the EN pin is kept high. The UVLO function protects against unstable operation at low Vin
levels .
Soft Start
The device has an internal soft-start function that limits the inrush current during start-up. The soft-start system
progressively increases the switching on-time from a minimum pulse-width to that of normal operation. Because of
this function, the output voltage increases gradually from zero to nominal voltage at start-up event. The nominal
soft-start time is 0.9msec. If you prefer a faster soft-start time, please contact a Murata representative.
Enable
The device starts operation when EN is set high and starts up with soft start. For proper operation, the EN pin must
be terminated to logic high and must not be left floating. If the pin is left open, the device may operate at light load
but will not work at heavy load.
Pulling the EN pin to logic low forces the device into shutdown. The device does not have a discharge function
when it turns off. If you prefer a discharge function, please contact a Murata representative.
100% Duty Cycle Operation
The device can operate in 100% duty cycle mode, in which the high-side switch is constantly turned ON, thereby
providing a low input-to-output voltage difference.
When Vin and Vout become close and the duty cycle approaches 100%, the switching pulse will skip the nominal
switching period and the output voltage ripple may be larger than other conditions. It should be noted that this
condition does not mean a failure of the device.
Over Current Protection
When the output current reaches the OCP threshold, the device narrows the switching duty and decreases the
output voltage. If the OCP event is removed within the mask time (20usec typ), the output voltage recovers to the
nominal value automatically. If the OCP event continues over the mask time, the device will shutdown. After it is
shut down, it can be restarted by toggling the Vin or EN voltage.

The enable switch has three positions.
1. When it is toggled to “ON” side, the device starts operation.
2. When it is toggled to “OFF” side, the device stops operation and remains in shut down status.
3. When it is set to middle of “ON” and “OFF”, the EN pin floats and an external voltage can be applied to the
EN terminal pin on the EVB. If you don’t apply an external voltage to EN pin, the enable switch should not to
be set to the middle position.
※The 47uF capacitor is for the evaluation kit only, and has been added to compensate for the long test cables.
