RT6255B Overview
The RT6255A/B is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 5A output current from a 4.5V to 18V input supply. The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very pact solution. The RT6255A/B adopts Advanced Constant On-Time (ACOTTM) control architecture that provides ultrafast transient response...
