SY21282 Product details

Description

The SY21282 high efficiency synchronous step-up regulator operates using adaptive constant off-time and current mode control, and supports a wide input voltage range from 3V to 9V.

Features

cycle-by-cycle peak current limit, output short-circuit protection, and true shutdown. It also provides enable control and power-good indicator for system power sequencing. The 1MHz pseudo-constant frequency reduces the output voltage ripple and permits smaller external capacitors and inductor. The SY21282 is available in a compact QFN3×316 package. Features.
3V to 9V Input Voltage Range.
6A (Min. ) Main MOSFET Current Limit.
7 µA Shutdown Current (Max. ).
600 µA Quiescent Cur.
