SY21282 Datasheet Step-up Regulator

Manufacturer: Silergy

Overview: SY21282 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

Key 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.
