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.
