The DIO60010/A is available in two versions, forced pulse width modulation (FPWM) and Auto Mode.The

DIO60010/A is a synchronous buck regulator IC that integrates the adaptive constant-on-time (COT) control,

and 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 COT control, this regulator IC can achieve the highest efficiency

and the highest switch frequency simultaneously to minimize the external inductor and capacitor size, thus

achieving the minimum solution footprint. Under PWM mode, the converter operates with a typical 1.65 MHz

switching frequency to minimize the size of the inductor and capacitor. As the load current decreases, the

converter enters PSM (Power Save Mode), reducing the switching frequency to keep high efficiency over the

entire load current range.
