SD4948C is a DC-DC converter controller with built-in high-current MOSFETs, which can be used in buck, buck-boost, and flyback power systems.
The SD4948C has a built-in high-voltage power supply function for fast start-up and an adaptive frequency reduction function to optimize the conversion efficiency at light load. Built-in frequency jitter function to optimize EMI.
SD4948C integrates various protections, including: cycle-by-cycle peak current protection, VDD overvoltage protection, undervoltage protection, output overload protection, output overvoltage protection, overtemperature protection, etc.
