RT5796B 1.5A, 1MHz, 6V CMCOT Synchronous Step-Down Converter General Description The RT5796B is a high efficiency synchronous step-down DC/DC converter. Its input voltage range is from 2.5V to 6V and provides an adjustable regulated output voltage from 0.6V to 3.4V while delivering up to 1.5A of output current. The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The Current Mode Constant-On-time (CMCOT) operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT5796B is available in the T/SOT-23-5 and T/SOT-23-6 packages.
