LM5008SDX

Voltage Regulators - DC DC Switching Regulators Overview

The LM5008SDX/NOPB is a high-voltage step-down switching regulator from Texas Instruments. It operates with an input voltage range of 9.5V to 95V and provides an adjustable output voltage between 2.5V and 75V. The device delivers a maximum output current of 350mA through a single output channel. It utilizes a constant on-time control architecture with an external resistor-programmable switching frequency ranging from 50kHz to 600kHz. Packaged in an 8-pin WSON format, it supports surface-mount installation and functions within a temperature range of -40°C to +125°C.
