Descriptions
The DIO6971 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 3A output currents.
The DIO6971 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.
The COT architecture with Pseudo fixed switching
frequency operation provides fast transient
response and eases loop stabilization. Protection
features include over-current protection and
thermal shutdown.
The DIO6971 requires a minimal number of
readily-available, standard, external components
and is available in a space-saving TSOT23-6
package.
