PL8905 Overview
PL8905 is a high voltage Buck Control designed for high performance synchronous Buck DC/DC applications with input voltages up to 100V. PL8905 integrates a high efficiency synchronous step-down switching regulator, which includes a 120V, 17mΩ high side and a 120V, 17mΩ low side MOSFETs to provide 5A continuous load current over12V to 100V wide operating input voltage. PL8905 switching frequency is programmable from...
