LM2717MT

Voltage Regulators - DC DC Switching Regulators Overview

The LM2717MT is a dual step-down DC/DC switching regulator manufactured by Texas Instruments. It integrates two independent buck converters within a single package, providing fixed output voltages of 3.3V for both channels. The device supports input supply voltages ranging from 4V to 20V. Output current capabilities are rated at 2.2A for the first channel and 3.2A for the second channel. The internal switching frequency operates between 300kHz and 600kHz. It utilizes a 24-TSSOP surface-mount package with a width of 4.40mm. The component is designed for operation across an extended junction temperature range of -40°C to 125°C.
