Application Notes: AN_SY8204 High Efficiency Fast Response, 4A, 30V Input Synchronous Step Down Regulator General Description Features 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. • Low RDS(ON) for internal switches (top/bottom): 80/50 mΩ • 4.5-30V input voltage range • Instant PWM architecture to achieve fast transient responses • External softstart limits the inrush current • Pseudo-constant frequency: 500kHz at heavy loads • 4A continuous, 5A peak load current capability • 1.5% 0.6V reference • Output over current limit • Output short circuit protection with current fold back • Thermal shutdown and auto recovery • RoHS Compliant and Halogen Free • Compact package: SO8E 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.
