Design a Custom BoardAbout This Component
The AL3353 is a PWM boost LED controller for LCD backlighting applications, accepting 9-40V input and regulating LED current via current-mode control with 400mV feedback reference. It features PWM-to-analog dimming capability and comprehensive protections including OCP, OVP, LED open/short detection, and thermal shutdown. Ideal for LCD TV and monitor backlight systems.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
