DPA425 - Highly Integrated DC-DC Converter ICs

Download the DPA425 datasheet PDF. This datasheet also covers the DPA423 variant, as both devices belong to the same highly integrated dc-dc converter ics family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
