Descriptions
The DIO6970 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 2A output currents.
The DIO6970 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.
DIO6970 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.
