DESCRIPTION
SPM1004 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.
Only one external input capacitor and one external output
capacitor are needed for typical applications. There is no
need for loop compensation, sensitive PCB layout,
inductor selection, or in-circuit production testing.
SPM1004 integrated POL power module series are offered
with eight models for eight different output voltages:
5.0V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 1.0V, and 0.8V. Each
output voltage can be trimmed by ±10%.
All SPM1004 models deliver full 6A load current without
derating at 85°C ambient temperature with no airflow.
Small size (15mm x 9mm) and low profile (3mm) allows
SPM1004 to be placed very close to its load or on the back
side of the PCB for high density applications.
Constant-on-time (COT) control is used to achieve
excellent transient response to line and load changes
without sacrificing stability and high efficiency at light
load.
Sumida's PSI² technology ensures optimal inductor design,
uniform temperature distribution and very low
temperature difference between case and IC die.
