High Efficiency Fast Response, 2A, 18V Input
Synchronous Step Down Regulator
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.
