Application Notes: AN_SY8204 High Efficiency Fast Response, 4A, 30V Input Synchronous Step Down Regulator General Description SY8204 develops a high efficiency synchronous stepdown DC-DC converter capable of delivering 4A output current. SY8204 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. SY8204 adopts the proprietary instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of 500kHz under continous conduction mode to minimize the size of inductor and capacitor.
