PL5700 Description
The PL5700 adopts constant-on-time (COT) control topology, which provides fast transient response. The 2A gate driver minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices. Additionally, the PL5700 uses pulse-skip mode to improve the efficiency under light loads or no load.
