SY8113E1 Datasheet | Silergy

High Efficiency, Fast Response, 3.0A, 18V Input Synchronous Step Down Regulator General Description The SY8113E1 is a high efficiency, 500 k Hz synchronous step-down DC/DC regulator capable of delivering up to 3A load current. It can operate over a wide input voltage range from 4.5V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8113E1 adopts the instant PWM architecture to achieve fast transient responses for high step down applications. In addition, it operates at pseudoconstant frequency of 500 k Hz to minimize the size of the inductor and the capacitor.
