MYXPM6021*
1 General Description
*Advanced information. Subject to change without notice.
The MYXPM6021 PMIC is a monolithic single chip power management IC for the next generation Intel® Atom™ processor.
It provides all power supplies for tablet PC’s and can also be used in multiple embedded applications as well as Netbooks
and Nettops. It is designed to support platforms based on Intel’s new Atom processor series, including DDR3 memory
and various peripherals.
Integrated Power Management
Micross’ new MYXPM6021 uses a single supply voltage at a wide range of input voltage and provides low noise supplies
to all SoC voltage domains, DDR3 memory and many peripherals. The MYXPM6021 integrates 6 high performance low
dropout (LDO) voltage regulators using Micross’ patented Smart Mirror™ technology for very low quiescent current. It
includes 11 internal power switches and the control logic for 9 external switching devices. These include in-rush current
control for platform power distribution simplification. Six fully integrated high efficiency DC-DC buck converters provide
current to Intel Atom platform’s various low voltage domains as well as to the memory and the peripherals. Two buck-
boost and one boost converter also supply energy for the platform. All nine regulators are designed to support external
component height of 1mm.
Ultra Flexible Power Sequencer
The ultra-flexible power sequencer takes care of the complete platform start-up, state-transitioning and power down
procedure. The MYXPM6021 operates autonomously and reduces the power consumption when entering stand-by or
power down mode. The MYXPM6021 is fully programmable and allows adaption to all Intel Atom processor and platform
sequences. The OTP programmed power sequence is copied into operational registers during power-up. Those registers
can be overwritten by EEPROM after initial OTP copy routine or via operational processor.
Auxiliary Function
An analogue to digital converter (ADC) with 10-bit resolution combined with a multi-channel input multiplexer allows
measurement of the input supply voltage, battery ID, PMIC die temperature, as well as 5 battery pack and system
temperatures. The number of external components is significantly reduced due to the integration of 16 GPIO’s, 3 channel
PWM output signal generators, a multi-input detector with a charger control, as well as a programmable IRQ controller.
