SY8104 DC/DC降压IC 4A矽力杰电源芯片原装正品代理
税前: ¥1.50
General Description
The SY8104 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of
delivering 4.0A current. The SY8104 operates over a wide input voltage range from 4.5V to 16V
and integrates main switch and synchronous switch with very low RDS(ON)to minimize the
conduction loss.
Low output voltage ripple and small external inductor and capacitor sizes are achieved with 500
kHz switching frequency. It adopts the instant PWM architecture to achieve fast transient
responses for high step down applications
