Programmable Multi-Channel
PMIC with Distributed Power
Source Controller and SVID
Preliminary Overview
IDTP9145
Description
The IDTP9145 is a programmable, multiple channel power
management IC (PMIC) designed for the Intel
®
Atom™
SoC to meet high performance requirements and provide
high-feature integration to minimize system board area
and BOM cost.
The PMIC includes subsystems for voltage regulation,
power sequencing management, A/D conversion, GPIOs,
PWMs and others. The IDTP9145 device is controlled and
programmed by using an I2C that operates in-conjunction
with the SoC. There is also a serial voltage ID (SVID)
interface between the SoC and PMIC for handling VCC,
VNN & VDDQ voltage rail settings and system control
signals.
The output current capability of the IDTP9145 solution can
be increased by adding IDT’s intelligent, scalable,
distributed power sources (IDTP9147). These compact,
external devices provide up to 6 A of additional peak
current each. The IDTP9145 supports the connection of
up to eight external power sources, for 48 A of total
scalability.
Also included are 7 LDOs that are programmable over a
wide output voltage range and offer output currents up to
300mA. The LDOs are low noise, high PSRR and low
dropout regulators.
The default output voltages of all regulators as well as
device sequencing can be programmed by OTP (fuse
cells) for non-standard configurations, or can be
programmed on-the-fly in the application. The PMIC
operates from a single 4.5V to 5.5V supply.
The IDTP9145 utilizes an 8 x 8mm, 100-ld, dual row QFN
package and is guaranteed to operate over the
commercial temperature range of -40°C to +85°C.
