RT5707 Ultra-Low IQ HCOT Buck Converter Evaluation Board

Richtek’s RT5707 high-efficiency synchronous step-down converter features typical quiescent current. It provides high efficiency at light loads down to 10 mA and has an input voltage range of 2.2 V to 5.5 V. The RT5707 provides eight programmable output voltage 1.2 V to 3.3 V while delivering output current of up to 600 mA, peak to 1 A. The RT5707A provides eight programmable output voltage 0.7 V to 3.1 V while delivering output current up to 400 mA, peak to 0.5 A.

The hysteretic constant on-time (HCOT) operation with internal compensation allow the transient response to be optimized over a wide range of loads and output capacitors.

The EVB_RT5707WSC evaluation board is designed to demonstrate the capabilities of the RT5707. The evaluation board combines the RT5707 with external components to support up to 0.6 A of output current.
