RTQ2159-QA 8A, 6.5V, 2.1MHz, ACOT® Converter with I2C Interface General Description The RTQ2159 is a high-performance, synchronous step-down DC-DC converter that can deliver up to 8A output current from a 2.85V to 6.5V input supply. The output voltage can be programmed from 0.6V to 1.5V with I2C controlled 7-Bits VID. The device integrates low RDS(ON) power MOSFETs, accurate reference voltage and an integrated diode of bootstrap circuit to offer a very compact solution. The RTQ2159 adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultrafast transient response and further reduces the external-component count.
