LTC3824, High Voltage Step-Down Controller Delivers High Power with Minimum Number of Components

A typical LTC3824 application can deliver up to 2A of continuous load current, and provides up to 90% efficiency at 1A. Sturdy 2A, 8V gate drivers accommodate industrial high voltage P-channel MOSFETs. By using a P-FET as a main switch, the controller is able to operate up to 100% duty cycle, and does not require the boost capacitor and diode found in N-channel buck regulators
