DPA425 - Highly Integrated DC-DC Converter ICs

This page provides the datasheet information for the DPA425, a member of the DPA423 Highly Integrated DC-DC Converter ICs family.

Description

The DPA-Switch™ IC family is a highly integrated solution for DC-DC conversion applications with 16‑75 VDC input.

DPA-Switch uses the same proven topology as TOPSwitch™, cost effectively integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip.

Features

  • are enabled with three user configurable pins. Hysteretic thermal shutdown is also provided. In addition, all critical parameters (i. e. current limit, frequency, PWM gain) have tight temperature and absolute tolerance, to simplify design and reduce system cost. DPA-Switch VIN D RESET/ CLAMP.
