RT6243B Description
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 pact solution. The RT6243A/B adopts Advanced Constant On-Time (ACOTTM) control architecture that provides ultrafast...
