Descriptions
The DIO6922 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 2A continuous output
currents. The DIO6922 family operate 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.
DIO6922 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.
