STEVAL-SPDC01V2

STEVAL-SPDC01V1 STEVAL-SPDC01V2 10 A DC-DC high density PoL convert module demonstration boards based on the SPDC12L00010 Data brief Features ■ 10 A max output current ■ Input voltage range from 1.8 V to 14 V ■ Supply voltage range from 4.5 V to 14 V ■ Fixed or adjustable output voltage down to 0.6 V ■ Fixed frequency voltage mode control ■ Adjustable switching frequency ■ Soft-start and inhibit ■ Selectable UVLO threshold (5 V or 12 V bus) ■ Master/slave synchronization with 180° phase shift ) s ( ct u d o ■ Pre-bias startup capability ■ Selectable source/sink or source only capability after soft-start ■ Power Good output with programmable delay ■ Overvoltage protection with selectable latched/not-latched mode ■ Thermal shutdown ■ Operating temperature range from - 40 °C to 85 °C s ( t c u d o r P e bs AM02123v1 STEVAL-SPDC01V1 STEVAL-SPDC01V2 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. Pb-Free and RoHS compliant A built-in adjustable soft-start and inhibit guarantee correct functionality whatever the load is. 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, October 2009 t e l o O ) t e l o Description s b O ■ r P e 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.
