This document describes the features and characteristics of the ADP1853 model synchronous step-down DC-DC controller, including input voltage range, output voltage range, maximum output current, current mode architecture, output voltage accuracy, configurable frequency, synchronization input, power saving mode, enable input, overvoltage and overcurrent protection, thermal overload protection, etc.
The ADP1853 is a wide-range input, synchronous buck controller capable of operating from 2.75 V to 20 V inputs. It supports output voltages from 0.6 V to 90% of the input voltage with a maximum output current of more than 25 A. The device features a current mode architecture with valley current sensing for fast step response, though it can also be configured for voltage mode operation.
