Application Note: SY8288A
High Efficiency Fast Response 8A, 23V Input Synchronous Step Down Regulator
General Description
Features
The SY8288A develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 8A current. The device integrates a main switch and a synchronous switch with very low RDS(ON) to minimize the conduction loss.
The SY8288A operates over a wide input voltage range from 4V to 23V. The DC/DC regulator adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light load. The device provides various protection features for reliable operation. In addition, it operates at pseudo-constant frequency of 600 kHz to minimize the size of inductor and capacitor.
