The DALC208SC6 from STMicroelectronics is a low-cost, wide-range current-mode control five-pin device that provides intelligent control for DC/DC power supplies. It is designed to be used in applications such as PC peripherals and notebook PCs, and provides accurate current sensing and fast current control over a wide range of input and output voltages. It also has comprehensive protection features, such as under voltage lock out (UVLO) and power-saving functions. The device uses an external N-channel MOSFET for power switches. The control loop is easily adjustable via a single external resistor, allowing for a wide selection of transient response and current control characteristics. It also features other features, such as an open-drain fault indicator and an input voltage monitoring pin.
