DS4823-01 September 2022 www.richtek.com 1 Wide Input and Ultra-Low Quiescent Current Boost Converter with High Efficiency General Description The RT4823 integrates built-in power transistors, synchronous rectification, and low supply current to provide a compact solution for systems using advanced Li-Ion battery chemistries. The RT4823 is capable of supplying significant energy when the battery voltage is lower than the required voltage for system power ICs. The RT4823 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below system minimum. In boost mode, output voltage regulation is guaranteed to a maximum load current of 1500mA. Quiescent current in shutdown mode is less than 1 A, which maximizes the battery life. The regulator transitions smoothly between bypass and normal boost mode. The device can be forced into bypass mode to reduce quiescent current. The RT4823 is available in the WL-CSP-9B 1.3x1.2 (BSC) package.
