Design a Custom BoardAbout This Component
Offline LED driver IC supporting PWM dimming for isolated power factor correction applications. Integrates power MOSFET control with current regulation for LED string management in AC-DC converters. Typical applications include LED lighting systems, backlighting, and display drivers requiring isolated offline operation with programmable brightness control.
Package: MSOP-10 (P0.5mm) · 10 pins
Why does this need a breakout?
The 0.5mm pin pitch makes hand soldering impractical without specialized equipment, and the tiny 3x3mm footprint cannot connect directly to breadboards. A breakout board brings these pins to standard 0.1-inch spacing, enabling rapid prototyping of analog-to-digital converters, boost controllers, and audio switches without reflow soldering or custom PCBs.
