Design a Custom BoardAbout This Component
Pulse-width modulation controller IC for switching power supplies with dual output capability. Features programmable frequency up to 500kHz, integrated comparators, and error amplifier for closed-loop regulation. Commonly used in SMPS designs, DC-DC converters, and industrial power applications requiring independent control of two switching sections.
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.
