Typical Application

Application Information

DIO6010 is a synchronous buck regulator IC that integrates the PWM control, top and bottom switches on the

same die to minimize the switching transition loss and conduction loss. With ultra low RDS(ON) power switches and

proprietary PWM control, this regulator IC can achieve the highest efficiency and the highest switch frequency

simultaneously to minimize the external inductor and capacitor size, and thus achieving the minimum solution

footprint.

Because of the high integration in the DIO6010 IC, the application circuit based on this regulator IC is rather

simple. Only input capacitor CIN, output capacitor COUT, output inductor L and feedback resistors (R1 and R2)

need to be selected for the targeted applications specifications.

Feedback resistor dividers R1 and R2

Choose R1 and R2 to program the proper output voltage. To minimize the power consumption under light loads,

it is desirable to choose large resistance values for both R1 and R2. A value of between 10k and 1M is highly

recommended for both resistors. If Vout is 1.8V, R1=100k is chosen, then R2 can be calculated to be 50k.
