The RT5797A is a high efficiency synchronous step-down converter. Its input voltage range is from 2.7V to 6V, and it provides an adjustable regulated output voltage from 0.6V to 3.4V while delivering up to 3A of output current.The device integrates synchronous low on-resistance power switches, which enhance efficiency and eliminate the need for an external Schottky diode. Its 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 RT5797A is available in the WDFN-8L 2x2 and WDFN-8SL 2x2 packages.The recommended junction temperature range is -40°C to 125°C, while the ambient temperature range is -40°C to 85°C.
