LX1734 Datasheet (Microsemi Corporation) - 1.0MHz Inverting DC/DC Converter

LX1734, 1.0MHz Inverting DC/DC Converter

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 component size and cost by implementing a high switching frequency of 1.0MHz, while generating -5V at 250mA.

LX1734 Features

* Stable Operation With Ceramic or Tantalum Capacitors

* -5V at 250mA from 5V Input

* Uses Small Surface Mount L/C Components

* Wide Input Range: 4.2V to 8V

* Low VCESAT S
