RTQ2820A
Description
The RTQ2820A is a high-performance, synchronous step-down converter that can deliver up to 20A output current with a wide input supply voltage range of 3.5V to 17V. The device integrates low RDS(ON) power MOSFETs, an accurate 0.6V 1% reference over the full operating junction temperature range, and an integrated diode for the bootstrap circuit, offering a very pact solution.
The RTQ2820A adopts Advanced Constant-On-Time (ACOT® ) control architecture that provides excellent transient performance and reduces the count of external ponents. In steady states, the ACOT® can operate at nearly constant switching frequency over line, load and output voltage ranges, making the EMI filter design easier.
The device offers a variety of functions to provide more design flexibility. The selectable switching frequency, current limit level, PWM operation modes make the RTQ2820A easy-to-use over wide application range. An independent enable control input pin and power-good indicator are...
