Alfa-MOS Technology AF7115 1.5MHz, 1.5A / 5V Synchronous Step-Down Converter General Description AF7115 is a high efficiency step down DC/DC converter operated with current mode and constant frequency. The internal switch and synchronous rectifier are integrated for high efficiency. External Schottky diodes are not required. The supply current is 30µA (typ) during operation and drops to less than 1µA in shutdown. AF7115 The device operates from an input voltage range of 2.5V to 6.5V and provides an output voltage from 0.6V to VIN. The switching frequency is set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. It can run 100% duty cycle for low dropout application. Internal soft-start control circuitry reduces inrush current.
