The NH020-Series Power SIPs are nonisolated dc-dc converters that operate over an input voltage range of 4.5 Vdc to 5.5
Vdc and provide a precisely regulated dc output. The SIPs have a maximum output current rating of 6 A at a typical full-load
efficiency of 86%. Standard features include remote on/off and output voltage adjustment.

Overcurrent Protection
To provide protection in a fault condition, the unit is equipped
with internal overcurrent protection. The unit operates nor-
mally once the fault condition is removed.
The power module will supply up to 350% of rated current for
less than 1.25 seconds before it enters thermal shutdown.
Overtemperature Protection
To provide additional protection in a fault condition, the unit is
equipped with a nonlatched thermal shutdown circuit. The
shutdown circuit engages when Q1 or Q2 exceeds approxi-
mately 110 °C. The unit attempts to restart when Q1 or Q2
cool down and cycles on and off while the fault condition
exists. Recovery from shutdown is accomplished when the
cause of the overtemperature condition is removed.
