PT4210 Series —48V

Features

38V to 75V

Description

The PT4210 series of low-power

isolated DC-DC converters are pin-

compatible with Power Trends’ popular

PT4200 series. The PT4210 series has

improved load regulation over the

PT4200, and is a compatible alternative

for both new and existing designs.

Applications include Telecom and

Datacom systems where both board

space and height are a premium.

The PT4210 series is offered in both

through-hole or SMD-DIP package

types with single non-adjustable output

voltages of 3.3V, 5V, and 12V.
