| Description | High Voltage/ Dual Synchronous Buck Converter |
|
|
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 switching frequency can be synchronized to an external clock between 150kHz and 250kHz.
