Design a Custom BoardAbout This Component
Pulse-width modulation controller IC designed for use in switch-mode power supplies and DC-DC converters. Features dual outputs, on-chip oscillator, error amplifier, and adjustable deadtime control. Operates from 5V to 40V input, making it suitable for offline and isolated power supply applications requiring flexible frequency and duty-cycle regulation.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
