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.
