LP8755KMX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LP8755KMX/NOPB is a multi-phase step-down DC/DC converter manufactured by Texas Instruments. It integrates six independent buck converters within a single package, designed for high-current applications such as SD card power conversion. The device operates with an input voltage range of 2.5 V to 5 V and provides adjustable output voltages from 600 mV to 1.67 V. Each phase supports up to 15 A of output current, utilizing a fixed switching frequency of 3.4 MHz. The component functions reliably across an operating temperature range of -40°C to +85°C and is housed in a DSBGA-49 surface-mount package.
