The SY21712 develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 12A current. The device integrates high-side power switch and low-side synchronous rectifier with very low RDS(ON) to minimize the conduction loss. It provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over TJ= -40°C to 125°C.
The SY21712 operates over a wide input voltage range from 2.7V to 16V. The DC/DC regulator adopts the instant PWM architecture to achieve fast transient responses for high step down applications. Cycle-by-cycle current limit, hiccup over current protection and thermal shutdown protect the device during an over current condition
