SY8201ABC原装SILERGY矽力杰高效同步降压调节器芯片IC
税前: ¥1.20
General Description
SY8201 develops high efficiency synchronous step-down 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.
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.
