MYXPM9145 Programmable Multi-Channel PMIC Advanced information. Subject to change without notice. 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 Programmable mode selection: • Automatic PWM/PFM transition for high efficiency at light load or, • PWM mode only for low noise applications Two controllers with up to 24A output current per channel Three synchronous step down converters with 5A output current Two synchronous step down converters with 2.5A output current • 7 general purpose linear regulators • SVID interface supporting IMVP7 protocol • 10-bit ADC Monitors internal and external voltages, temperature, currents • Host interface and system management Interrupt controller with mask-able interrupts Reset function 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. Programmable sequencing of output rails 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 IDT Part.
