SY8120B1ABC SOT23-6 同步DC/DC降压稳压器 原装正品
税前: ¥0.50
General Description
SY8120B1 develops high efficiency synchronous step-down DC-DC converter capable of delivering 2A load current . SY8120B1 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to
minimize the conduction loss.
SY8120B1 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.
