Features and benefits

analog soft-start circuitry that is independent of the output load and output capacitance. This makes the soft-start behavior more predictable and controllable than tradi.

Description

The LM2642 consists of two current mode synchronous buck regulator controllers with a switching frequency of 300kHz. The two switching regulator controllers operate 180˚ out of phase. This feature reduces the input ripple RMS current, thereby signifi.
