The RT5716 is a high switching frequency synchronous step-down converter with a quiescent current of 2.3μA. The device uses RBCOT (Ripple-Based Constant-On-Time) control to enhance load/line transient response to be optimized over a wide range of loads and output capacitors.
The RT5716 input voltage range is from 1.8V to 5.5V, making it suitable for battery applications. It provides 16 selectable output voltage levels by connecting the resistor between RSEL/MODE pin and GND. The PFM design can maintain high efficiency during the light load. At higher load conditions, the device automatically switches to PWM. The device can deliver up to 0.6/1A loading current. In shutdown mode, the supply current is typically 55nA, excellent in reducing power consumption.
The RT5716 is available in TWL-CSP-6B 0.69x1.04 (BSC) and WDFN-6L 1.5x1.5 (FC) packages that have the smallest packages for small size applications.
The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
