® RTQ2822A/B 12A, 17V, High Efficiency Synchronous Step-Down Converter General Description The RTQ2822A/B is a high-performance, synchronous step-down 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 RTQ2822A/B adopts Advanced Constant On-Time (ACOT®) control architecture that provides ultrafast transient response and further reduce the externalcomponent count. In steady states, the ACOT®operates in nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier.
