DESCRIPTION
The LANEUW series consists of isolated 2 Watt DC/DC power converters with fully regulated single and dual
outputs and ultra wide 4:1 input voltage ranges of 9~36VDC and 18~75VDC. These converters operate over a
temperature range of -40°C to +85°C while maintaining all specifications. The LANEUW series is RoHS
compliant and includes remote on/off control, 1500VDC I/O isolation, and over load protection. These converters
are housed in a 9-pin SIP package with a very small footprint occupying only 0.36in2 on the PCB. The very
compact dimensions of these DC/DC converters make them an ideal solution for many space critical applications
in battery-powered equipment and instrumentation.

NOTES
1. These power converters require a minimum output loading to maintain all specified regulations. Operation under no-load
conditions will not damage these devices; however, they may not meet all the listed specifications.
2. All DC/DC converters should be externally fused at the front end for protection.
*Due to advances in technology, specifications are subject to change without notice.

TEST CONFIGURATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7µH) and Cin (220µF, ESR < 1.0Ω at 100 KHz)
to simulate source impedance. Capacitor Cin offsets possible battery impedance.
Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0-500 KHz.
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement
bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC Converter.
DESIGN & FEATURE CONSIDERATIONS
Remote On/Off
Negative logic remote on/off turns the module OFF during a logic high voltage on the remote on/off pin and ON
during a logic low. To turn the module ON and OFF, the user must supply a switch to control the voltage between
the on/off terminal and the –Vin terminal. The switch can be an open collector or equivalent. A logic high is 2.9V
to 15V. A logic low is under 0.6VDC or open circuit, drops down to 0VDC by 2mV/°C. The maximum sink current
at on/off terminal during a logic low is 1mA. The maximum allowable leakage current of the switch at on/off
terminal = (under 0.6VDC or open circuit) is 1mA.
Maximum Capacitive Load
The LANEUW series has a limitation of maximum connected capacitance on the output. The power module may
be operated in current limiting mode during start-up, affecting the ramp-up and the start-up time. The maximum
capacitance can be found in the model selection tables.
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting
circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit
shifts from voltage control to current control. The unit operates normally once the output current is brought back
into its specified range.

Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances
can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary to use a
capacitor at the input to ensure startup.
Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good
quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of 1.5µF for the 24V and 48V input
devices.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise
performance. To reduce output ripple, it is recommended to use 3.3µF capacitors at the output.
Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module,
and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power
module, the case temperature must be kept below 90°C. The derating curves are determined from measurements
obtained in a test setup.
