LM2853MHX-2.5

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MHX-2.5 is a synchronous step-down DC-DC converter manufactured by Texas Instruments, designed for high-efficiency power management in compact applications. It integrates a 3A output current capability with a fixed switching frequency of 550 kHz to minimize external component size. The device operates within an input voltage range of 3V to 5.5V and provides a fixed 2.5V output. Packaged in a 14-pin HTSSOP with an exposed pad for thermal dissipation, it supports operation across an extended temperature range of -40°C to +125°C.
