LSP3170 - 2A Step Down DC/DC Converter

This page provides the datasheet information for the LSP3170, a member of the LSP3170-Lite 2A Step Down DC/DC Converter family.

Description

The LSP3170 is a current-mode step-down DC/DC converter that generates up to 2A of output current at 400kHz switching frequency.

Consuming only 40µA in shutdown mode, the LSP3170 is highly efficient with peak operating efficiency at 95%.

Features

  • 2A Output Current Up to 95% Efficiency 4.6V to 24V Input Range 40µA Shutdown Supply Current 400kHz Switching Frequency Adjustable Output Voltage Cycle-by-Cycle Current Limit Protection Thermal Shutdown Protection Frequency Foldback at Short Circuit Stability with Wide Range of Capacitors, Including Low ESR Ceramic Capacitors SOP8L Package.
