Introduction

AI Translation

LM26480 is a multi-functional power management unit (PMU) optimized for low-power digital applications. This device integrates two high-efficiency 1.5A step-down DC/DC converters and two 300mA linear regulators. The DC/DC step-down converters offer a typical efficiency of 96%, enabling minimum power consumption. The device provides soft-start, undervoltage lockout, current overload protection, thermal overload protection functions, and also features an internal power-on reset (POR) circuit to monitor the output voltage levels on Buck converters 1 and 2.
