SY8105原装正品 矽力杰 DC-DC降压芯片5A电源IC
税前: ¥1.50
General Description
The SY8105 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of
delivering 5.0A current. The SY8105 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. 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
