Description

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.

Absolute Maximum Ratings

NH020-Series Power SIPs:

5 Vdc Input; 1.5 Vdc to 3.3 Vdc Output; 20 W

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress

ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the

operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the

device reliabiltiy.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power SIP can be used in a wide variety of applications, ranging from simple stand-alone operation to an

integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however,

to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow

fuse with a maximum rating of 10 A (see Safety Considerations section). To aid in the proper fuse selection for the given appli-

cation, information on inrush energy and maximum dc input current is provided. Refer to the fuse manufacturer’s data for fur-

ther information.
