SY21107 Datasheet | Silergy

General Description The SY21107x is high efficiency synchronous buck converter operates over a wide input voltage range of 4.5V to 18V, and can deliver an output current up to 2A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss. The high pseudo-constant switching frequency enables using small external inductor and capacitor values. The device uses constant on-time and ripple-based control strategy to achieve fast transient response for applications with high step-down ratios. It also provides cycle-by-cycle current limit protection, output under voltage protection and over temperature protection. Only the input and output capacitors,...
