EVAL6926D: 1.8V @ 800mA, 2 ~ 5.5 Vin

This application note details the main features and application advantages of this new synchronous step-down regulator.

After describing how the device works and the main features, a step-by-step design section is provided in order to aid in the selection of the external components and in the evaluation of the losses. The device performances are shown in terms of efficiency and thermal results.

This product, designed using BCDV technology, is a high efficiency monolithic synchronous step-down regulator capable of delivering up to 800 mA of continuous output current and to regulate the output voltage from 0.6 V up to VIN thanks to the 100% duty cycle operation capability.

The input voltage ranges from 2 V to 5.5 V. The control loop architecture is based on a constant frequency peak current mode, while high efficiency at light loads is achieved by a low consumption functionality.
