® 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.
