STEVAL-SPDC01V1 STMicroelectronics

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 AM02123v1 shift Pre-bias startup capability STEVAL-SPDC01V1 STEVAL-SPDC01V2 Selectable source/sink or source only without external heat sink or airflow. The device is capability after soft-start a complete standalone surface mount power Power Good output with programmable delay supply, that can be handled and assembled like a Overvoltage protection with selectable standard integrated circuit. Moreover its low latched/not-latched mode profile design permits to be soldered onto the back side of a printed circuit board, freeing up Thermal shutdown valuable board space. Operating temperature range from - 40 C to 85 C 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 Description is. The boards are based on a single module Pre-bias start up capability is in place as well SPDC12L00010, high density 10 A DC-DC Power Good output with programmable delay to converter, that implements a complete step-down avoid false signals. power supply. The device is packaged in a thermally enhanced, A single LGA package includes ST switching compact (15 x 15 mm) and low profile (3 mm) controller, power FETs, inductor and all the overmolded land grid array (LGA) package, support components and it is able to operate over suitable for automated assembly by standard a wide input voltage range of 1.8 V to 14 V, surface-mount equipment. supporting an output range of 0.6 V to 5 V. High level of integration and synchronous rectification The demonstration boards are an essential tool allows this module to deliver up to 10 A for testing the module and it is Pb-Free and RoHS continuous current at up to 93% efficiency, compliant.
