Descriptions

The DIU6921 is a high-efficiency, high-frequency

synchronous step-down DC-DC regulator IC

capable of delivering up to 2 A output currents.

The DIU6921 operates over a wide input voltage

range from 4.5 V to 30 V and integrates the main

switch and synchronous switch with very low

RDS(ON) to minimize the conduction loss.

The DIU6921 adopts the COT architecture to

achieve fast transient responses for high

step-down applications and high efficiency at

light loads. In addition, it operates at a

pseudo-constant frequency of 700 kHz under

heavy load conditions to minimize the size of the

inductor and capacitor.
