Description

The NH033x-L and NH050x-L Series Power Modules are non-isolated dc-dc converters that operate over an

input voltage range of 4.5 Vdc to 5.5 Vdc and provide a regulated output between 1.2 V and 3.3 V. The open

frame power modules have a maximum output current rating of 10 A and 15 A, respectively, at typical full-load

efficiencies of 91%.
