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.
