RT7291A - Synchronous Buck Converter

General Description

The RT7291A/B is a synchronous Buck converter with Advanced Constant On-Time (ACOT®) mode control.

The main control loop of the RT7291A/B uses an ACOT® mode control which provides a very fast transient response with no external compensators.

Key Features

  • 5V to 23V Input Voltage Range.
  • Up to 98% Duty for 2S Battery.

® RT7291A/B 6A, 23V, 500kHz, ACOT® Synchronous Buck Converter with LDO for System 5V General Description The RT7291A/B is a synchronous Buck converter with Advanced Constant On-Time (ACOT®) mode control. The main control loop of the RT7291A/B uses an ACOT® mode control which provides a very fast transient response with no external compensators. The RT7291A/B operates from 5V to 23V input voltage, provides a 5V LDO and a 300kHz CLK to drive an external charge pump. OCP, UVP and OVP are included in the RT7291A/B. This IC also provides a 1.5ms internal soft-start function and an open-drain power good indicator.
