SY8368A 8A大电流同步降压芯片DC/DC矽力杰原装正品代理
税前: ¥4.00
General Description
The SY8368A develops a high efficiency synchronous step-down DC-DC regulator capable of
delivering 8A continuous, 16A peak current. The SY8368A operates over a wide input voltage
range from 4.0V to 28V and integrates main switch and synchronous switch with very low
RDS(ON) to minimize the conduction loss.
The SY8368A 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 800kHz under continuous conduction mode to minimize the size of
inductor and capacitor.
