The SY82852G high-efficiency 3.3V fixed output synchronous buck converter operates over a wide input voltage range of 4.5V to 30V, and can deliver an output current up to 0.6A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss. The 1100kHz pseudo-constant switching frequency enables using small external inductor and capacitor values.
