Features
Description
• Tin-lead ball metallurgy
The MYXP9145 is a programmable, multiple channel Power
Management Integrated Circuit (PMIC) designed for the Intel®
Atom™ SoC to meet high performance requirements, as well
as, to provide high-feature integration to minimize system board
area and BOM cost.
• 7 programmable step-down switching regulators
ƒƒ Programmable mode selection:
• Automatic PWM/PFM transition for high efficiency
at light load or,
• PWM mode only for low noise applications
ƒƒ Two controllers with up to 24A output current per channel
ƒƒ Three synchronous step down converters with 5A output
current
ƒƒ Two synchronous step down converters with 2.5A output
current
• 7 general purpose linear regulators
• SVID interface supporting IMVP7 protocol
• 10-bit ADC
ƒƒ Monitors internal and external voltages, temperature,
currents
• Host interface and system management
ƒƒ Interrupt controller with mask-able interrupts
ƒƒ Reset function
ƒƒ Power control state machine
The PMIC includes subsystems for voltage regulation, power
sequencing management, A/D conversion, GPIOs, PWMs
and others. The MYXP9145 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 MYXP9145 is capable of providing current levels sufficient
for entry level applications with its internal regulators and is
capable to support higher current requirements by adding
Micross Components unique Smart Power Modules (IDTP9147/
IDT9148) to source additional current for those DCDC regulators.
Also included are 7 LDOs that are programmable over a wide
output voltage range and offer output currents up to 425mA.
The LDOs are low noise, high PSRR and good transient
response.
The default output voltages of all regulators as well as device
sequencing can be programmed by OTP (at the factory) to adjust
to non-standard configurations. The PMIC operates from a single
5V supply.
ƒƒ Programmable sequencing of output rails
ƒƒ High speed I2C interface (3.4Mbit/s)
• Enable outputs for external switches
• Sixteen programmable GPIOs
• -40°C to +85°C operating temperature range
• Available in thermally enhanced 100-ld, 8mm x 8mm x
0.7mm dual row QFN
