The RT6243A/B is a high-performance, synchronous stepdown
converter that can deliver up to 12A output current
with an input supply voltage range of 4.5V to 17V. The
device integrates low RDS(ON) power MOSFETs, accurate
0.6V reference and an integrated diode for bootstrap circuit
to offer a very compact solution.
The RT6243A/B adopts Advanced Constant On-Time
(ACOTTM) control architecture that provides ultrafast
transient response and further reduce the externalcomponent
count. In steady states, the ACOTTM operates
in nearly constant switching frequency over line, load and
output voltage ranges and makes the EMI filter design
easier.RT6243AGQVF RT6243BGQVF资料下载
