SPM1005  
3.3V/5V Input 6A Output Power Supply in Inductor (PSI2) Module  
FEATURES  
DESCRIPTION  
Integrated Point of Load power module using PSI2  
Power Supply in Inductor technology  
Small footprint, low-profile, 11mm x 9mm x 3mm,  
with LGA Package (0.63 mm Pads)  
SPM1005 is an easy-to-use 6A output integrated Point of  
Load (POL) power supply module. It contains integrated  
power MOSFETs, driver, PWM controller, a high  
performance inductor, input and output capacitors and  
other passive components in one low profile LGA package  
using PSI2 technology.  
Efficiency up to 96%  
High output current, 6A without derating at 85°C  
ambient with no air flow  
Only one input capacitor and one output capacitor are  
needed for typical applications. There is no need for loop  
compensation, sensitive PCB layout, inductor selection or  
in-circuit production testing. Each module is fully tested.  
Wide output voltage adjustment: 0.6V to 3.6V  
Pre-bias startup capability  
User adjustable switching frequency  
Synchronization to external clock signal  
Adjustable soft-start time for output voltage  
Output voltage sequencing / tracking  
Enable signal input and Power Good signal output  
Programmable Under Voltage Lock Out (UVLO)  
Output Over Current Protection (OCP)  
Over temperature protection  
SPM1005 integrated POL module series are offered in two  
versions: universal output voltage version (SPM1005-Z)  
and single voltage version. With the SPM1005-Z version,  
the user can select the output voltage and switching  
frequency with external resistors. The single voltage  
versions provide fixed output voltage at 3.3V, 2.5V, 1.8V,  
1.5V, 1.2V, 1.0V, 0.8V or 0.6V. The user can trim the  
output voltage by ±10% using an external resistor.  
Operating temperature range -40°C to 85°C  
Qualified to IPC9592B, Class II  
MSL3 and RoHS compliant  
All SPM1005 models deliver full 6A load current without  
derating at 85°C ambient temperature with no airflow.  
Small size (11mm x 9mm) and low profile (3mm) allows  
the SPM1005 to be placed very close to its load or on the  
back side of the PCB for high density applications.  
Sumida's PSI2 technology ensures optimal inductor  
design, uniform temperature distribution and very low  
temperature difference between case and IC die.  
APPLICATIONS  
Broadband and communications equipment  
DSP and FPGA Point of Load applications  
High density distributed power systems  
Systems using PCI / PCI express / PXI express  
Automated test and medical equipment
