SY8201ABC数据手册Silergy中文资料规格书

描述 Description

SY8201 develops high efficiency synchronous stepdown DC-DC converter capable of delivering 1A .SY8201 operates over a wide input voltage range from 4.5V to 27V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.\r
\r
SY8201 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.
