Descriptions
The DIO6912 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 2 A continuous output
currents. The DIO6912 operates 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 DIO6912 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 pseudo-constant
frequency of 500 kHz under heavy load conditions
to minimize the size of inductor and capacitor.
