Introduction
The LTC3626 synchronous buck regulator with current and temperature monitoring is the first of Linear’s SWITCHER+ line of monolithic regulators. It is a high efficiency, monolithic synchronous step-down switching regulator capable of delivering a maximum output current of 2.5A from an input voltage ranging from 3.6V to 20V (circuit shown in Figure 33.1). The LTC3626 employs a unique controlled on-time/constant frequency current ...
