The RT7291A/B is a synchronous Buck converter with
Advanced Constant On-Time (ACOTTM) mode control. The
main control loop of RT7291A/B uses an ACOTTM 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. RT7291AGQUF RT7291BGQUF资料下载
