RTQ2822A
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 pact solution.
The RTQ2822A/B adopts Advanced Constant On-Time (ACOT®) control architecture that provides ultrafast transient response and further reduce the externalponent 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.
The device offers a variety of functions for more design flexibility. The selectable switching frequency, current limit level and PWM operation modes makes the RTQ2822A/B easy-to-use over wide application range. Independent enable control input pin and power good indicator are also provided for easy sequence control. To control the inrush current...
