Datasheet Summary
High Efficiency 1MHz, 16V, 6A Synchronous Step-Up Regulator with Accurate Output Current Limit
General 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. It integrates switches with low RDS(ON) to minimize conduction loss.
The SY21282 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.
