The PW2163 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of
delivering 3A current. The PW2163 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
