Description The boards are based on a single module SPDC12L00010, high density 10 A DC-DC converter, that implements a complete step-down power supply. A single LGA package includes ST switching controller, power FETs, inductor and all the support components and it is able to operate over a wide input voltage range of 1.8 V to 14 V, supporting an output range of 0.6 V to 5 V. High level of integration and synchronous rectification allows this module to deliver up to 10 A continuous current at up to 93% efficiency, without external heat sink or airflow. The device is a complete standalone surface mount power supply, that can be handled and assembled like a standard integrated circuit. Moreover its low profile design permits to be soldered onto the back side of a printed circuit board, freeing up valuable board space. The SPDC12L00010 is self-protected against overvoltage and short-circuit conditions. A built-in adjustable soft-start and inhibit guarantee correct functionality whatever the load is. Pre-bias start up capability is in place as well Power Good output with programmable delay to avoid false signals. The device is packaged in a thermally enhanced, compact (15 x 15 mm) and low profile (3 mm) overmolded land grid array (LGA) package, suitable for automated assembly by standard surface-mount equipment. The demonstration boards are an essential tool for testing the module and it is Pb-Free and RoHS compliant.
