Tiny, 360nA Low Quiescent Current, 0.5A/1A HCOT nanoPower Buck Converter

RT5713/RT5714

The RT5713/14 is a high efficiency synchronous step-down converter featuring typ. 360nA quiescent current. It provides high efficiency at light load down to 10mA. Its input voltage range is from 2.2V to 5.5V. The RT5713/14 provides 2 level output voltages which can be programmed via the voltage select pin VSEL while delivering output current up to 0.5A/1A.

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 RT5713/14 is a available in WL-CSP-6B 1.415x0.885 (BSC) and WDFN-6L 2x2 package.
