Design a Custom BoardAbout This Component
High-current boost converter IC for driving white LED strings up to 38V with integrated 40V, 1.8A MOSFET. Features PWM brightness control, open LED protection, and operates from 2.7-5.5V input at 1.2MHz switching frequency with up to 90% efficiency. Designed for smartphone and tablet backlighting, portable displays, and handheld medical equipment applications.
Package: SOT-353 · 5 pins
Why does this need a breakout?
SOT-553 packages like single-gate logic and LDO regulators are too small and fine-pitched for reliable hand-soldering or breadboard use. A breakout board brings these components to standard headers, enabling quick prototyping without reflow equipment. Essential for evaluating compact logic functions and power management ICs in development.
