Descriptions
The DIO6920 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 2A output currents. The
DIO6920 family operates over a wide input voltage
range from 4.5V to 24V and integrate main switch
and synchronous switch with very low RDS(ON) to
minimize the conduction loss.
DIO6920 adopts the COT 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 500kHz under heavy load conditions to
minimize the size of inductor and capacitor.
