LT3580 - Boost/Inverting DC/DC Converter

General Description

The LT®3580 is a PWM DC/DC converter containing an internal 2A, 42V switch.

The LT3580 can be configured as either a boost, SEPIC or inverting converter.

12V at 350mA from a 5V input, the LT3580 is ideal for many local power supply designs.
