Descriptions

The DIO6920H is high-efficiency, high frequency

synchronous step-down DC-DC regulator ICs

capable of delivering up to 2 A output currents.

The DIO6920H 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 DIO6920H 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.
