Descriptions

The DIG69130 is a high-efficiency, high-frequency

synchronous step-down DC-DC regulator IC

capable of delivering up to 3 A output currents.

The DIG69130 family operates over a wide input

voltage range from 4.5 V to 24 V and integrates

with the 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 overcurrent protection and

thermal shutdown.

The DIG69130 requires a minimal number of

readily-available, standard, external components

and is available in a space-saving TSOT23-6

package.
