主要应用
概述
SY8100 develops high efficiency synchronous step-down DC-DC converter capable of delivering 1.2A continous, 1.5A peak load current . SY8100 operates over a wide input voltage range from 4.5V to 16V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
SY8100 adopts the 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 500 kHz under heavy load conditions to minimize the size of inductor and capacitor.
