XR-2230, Pulse-Width Modulator Control System

The XR-2230 is a high-performance monolithic pulse width modulator control system.

It contains all the necessary control blocks for designing switch mode power supplies, and other power control systems.

Included in the 18-Pin dual-in-line package are two error amplifiers, a sawtooth generator, and t

XR-2230 Features

* such as adjustable dead-time control, thermal shutdown, soft-start control, and double-pulse protection circuitry. The device provides two open-collector output transistors which are driven 180° out-of-phase, and are capable of sinking 30 mA. These outputs can be used to implement single-ended or p
