RTQ2820A 20A, 17V, ACOT® High-Efficiency Synchronous Step-Down Converter 1 General 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 compact solution. The RTQ2820A adopts Advanced Constant-On-Time (ACOT® ) control architecture that provides excellent transient performance and reduces the count of external components.
