μPOL™ product family represents a new type of DC-DC converters. This is designed to power modern microprocessors, microcontroller, ASIC, FPGA, DSP and advanced digital logic devices. The increasing demand for high performance, fast load transient and voltage accuracy in small footprint are driving factor for this new innovation. μPOL™ technology offers an integrated solution including Power Semiconductor and Inductor in a very compact solution and with its I2C communication the device is configurable for a vast range of applications. This is a wide input range , non-isolated Step Down Converter (Buck converter), the output voltage can be configured from 0.6V to 5V using serial communication (I2C) without a need of any external components. The Stability of converter is ensured internally, thus no need for external compensation. Lots of design efforts have been made in order to make this device easy to use, system designers need to only add input and output capacitors to have a complete DC-DC converter.
