DPA425 Highly Integrated DC-DC Converter ICs

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. Hi.

DPA422-426 DPA-Switch Family Highly Integrated DC-DC Converter ICs for Power over Ethernet & Telecom Applications Product Highlights Highly Integrated Solution Eliminates up to 50 external components saves space, cost Integrates 220 V high frequency MOSFET, PWM control Lower cost plastic DIP surface mount (G package) and through-hole (P package) options for designs ≤35 W Thermally efficient TO-263-7C (R package) option for high power application.

DPA425 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.
