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.
