Description

The DPA-Switch IC family introduces a highly integrated solution DPA426 for DC-DC conversion applications in the 16-75 VDC input range.

DPA-Switch uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. High performance features are enabled with three user configurable pins.
