LAN K series of DC/DC converters provide 2~4 watts of continuous output power in a low profile DIP
package. These converters operate over 2:1 input voltage ranges of 4.5~9VDC, 9-18VDC, 18-36VDC,
and 36-75VDC and 4:1 input voltage ranges of 9-36VDC and 18-75VDC. This series also has standard
single output voltages of 3.3, 5, 12, 15VDC and dual output voltages of ±5, ±12, and ±15VDC. Some
features include continuous short circuit protection, 1500VDC I/O isolation, -25°C~+71°C operating

(4)
Transient recovery time is measured to within 1% error for a step change in output load of 50% to 100%.
The LAN K series requires a 10% minimum load on the output to maintain specified regulation. Operation under no-load conditions will not
damage these devices, however they may not meet all listed specifications.
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.

DESIGN & FEATURE CONSIDERATIONS
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 8.2µF for the 5V input devices, a 3.3µF for the 12V input devices, and a 1.5µF
for the 24V and 48V devices.

Maximum Capacitive Load
The LAN K series has a limitation of maximum connected capacitance at the output. The power module may be operated in current
limiting mode during start-up, affecting the ramp-up and the startup time.
For optimum performance we recommend 1000µF maximum capacitive load for dual outputs and 4000µF capacitive load for single
outputs.
Over Current Protection
To provide protection in a fault (output over load) 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 shifts from voltage control to current control. The unit
operates normally once the output current is brought back into its specific range.

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 100KHz) 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.

A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise performance. To reduce

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 90ºC. The derating curves are determined from measurements obtained in an experimental apparatus.
