The RT5716 is a high switching frequency synchronous step-down converter with a quiescent current of 2.3μA. The device uses Ripple-Based Constant-On-Time (RBCOT) control to enhance load and line transient response, optimizing performance over a wide range of loads and output capacitors.The RT5716 has an input voltage range from 1.8V to 5.5V, making it suitable for battery applications. It provides 16 selectable output voltage levels by connecting a resistor between RSEL/MODE pin and GND. The Pulse Frequency Modulation (PFM) design maintains high efficiency during light loads. While at higher load conditions, the device automatically switches to PWM. The device can deliver up to 1A loading current. In shutdown mode, the supply current is typically 55nA, which is excellent for reducing power consumption.The RT5716 is available in TWL-CSP-6B 0.69x1.04 (BSC) and WDFN-6L 1.5x1.5 (FC) packages, which are 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.
