Descriptions

The DIG69200 is high-efficiency, high frequency

synchronous step-down DC-DC regulator ICs

capable of delivering up to 2 A output currents.

The DIG69200 family operate over a wide input

voltage range from 4.5 V to 24 V and integrate

main switch and synchronous switch with very

low RDS(ON) to minimize the conduction loss.

The DIG69200 adopts 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 500 kHz under heavy load conditions

to minimize the size of inductor and capacitor.
