LM5642

High Voltage/ Dual Synchronous Buck Converter

LM5642 Features

* analog soft-start circuitry that is independent of the output load and output capacitance making the soft-start behavior more predictable and controllable than traditional soft-start circuits. Over-voltage protection is available for both outputs. A UVDelay pin is also available to allow delayed shu

LM5642 General Description

The LM5642 consists of two current mode synchronous buck regulator controllers operating 180˚ out of phase with each other at a normal switching frequency of 200kHz. Out of phase operation reduces the input ripple RMS current, thereby significantly reducing the required input capacitance. The switch.
