LX1734 Datasheet 1.0mhz Inverting DC/dc Converter

Manufacturer: Microsemi (now Microchip Technology)

LX1734 Overview

The LX1734 is an inverting DC/DC current-mode controller. With a 750mA integrated switch, the LX1734 can generate large output currents in a small footprint. The LX1734 minimizes external ponent size and cost by implementing a high switching frequency of 1.0MHz, while generating -5V at 250mA.
