Introduction

AI Translation

The TPS61023 is a synchronous boost converter with an ultra-low input voltage of 0.5V. The device provides a power solution for portable and smart devices powered by various batteries and supercapacitors. Across the full temperature range, the TPS61023 has a typical valley switch current limit of 3.7A. Over a wide input voltage range of 0.5V to 5.5V, the TPS61023 supports supercapacitor backup power applications, which may result in deep discharge of the supercapacitor. When the input voltage is above 1.5V, the TPS61023 operates at a switching frequency of 1MHz. When the input voltage drops below 1.5V and down to 1V, the switching frequency gradually decreases to 0.5MHz. The TPS61023 enters power save mode (PFM) under light load conditions to maintain high efficiency across the full load current range. Under light load conditions, the TPS61023 draws 20μA of quiescent current through Vout. During shutdown, the TPS61023 is fully disconnected from the input supply and consumes only 0.1μA to maximize battery life. The TPS61023 features 5.7V output overvoltage protection, output short-circuit protection, and thermal shutdown protection. The TPS61023 is available in a 1.2mm x 1.6mm SOT563 (DRL) package, minimizing the number of external components for a very compact solution footprint.
