Design a Custom BoardAbout This Component
High-efficiency boost converter IC designed for single-cell Li-Ion battery applications operating from 1.8V to 5.5V input. Delivers up to 2.1A output current with adjustable output voltage (1.8V-5.5V) and achieves up to 96% efficiency using CMCOT topology. Integrates internal power transistors, synchronous rectification, and comprehensive protection features including output overvoltage, short-circuit, and true load disconnect.
Package: TSOT-23-8 · 8 pins
Why does this need a breakout?
The 0.95mm pin pitch and compact footprint make hand-soldering extremely difficult and breadboard incompatible. A breakout board brings all eight pins to standard headers, enabling reliable prototyping of precision analog ICs like DACs, op-amps, and current-sense amplifiers without specialized soldering equipment.
