　　The PF0200 Power Management Integrated Circuit (PMIC) provides a highly programmable/ configurable architecture, with fully integrated power devices and minimal external components. With up to four buck converters, one boost regulator, six linear regulators, RTC supply, and coin-cell charger, the PF0200 can provide power for a complete system, including applications processors, memory, and system peripherals, in a wide range of applications. With on-chip One Time Programmable (OTP) memory, the PF0200 is available in pre-programmed standard versions, or non-programmed to support custom programming. The PF0200 is especially suited to the i.MX 6SoloLite, i.MX 6Solo and i.MX 6DualLite versions of the i.MX 6 family of devices and is supported by full system level reference designs, and pre-programmed versions of the device. This device is powered by SMARTMOS technology.

　　评估板KITPF0200EPEVBE

　　The KITPF0200EPEVBE evaluation board allows full evaluation capability of the MMPF0200 PMIC for the i.MX family of application processors. It provides access to all output voltage rails as well as control and signal pins through terminal block connectors for an easier out-of-the-box evaluation experience. A single terminal block connector for the input power supply allows the user to supply the board with an external DC power supply to fully evaluate the performance of the device.

　　The KITPF0200EPEVBE comes with a non-programmed version of the MMPF0200 PMIC, and it is configured to power up from the default power-up sequence. However, an integrated control/fuse programming interface is provided to allow the customer to program the OTP/TBB (One Time Programmable/Try-Before-Buy) memory and select it as the default source for the power-up configuration. Likewise, the programming interface allows full control of the MMPF0200 through the I2C communication lines.

　　评估板KITPF0200EPEVBE主要特性:

　　Input voltage operation range from 3.1 to 4.5 V

　　Output voltage supplies accessible through detachable terminal blocks

　　Three to four independent buck converters

　　One 5.0 V boost regulator

　　Six general purpose LDO regulators

　　One DDR memory termination voltage reference

　　One VSRTC supply

　　Coin cell support for “Try-Before-Buy” (TBB) mode

　　On/off push button support

　　Hardware configuration flexibility through various jumper headers and resistors

　　Integrated USB to I2C programming interface for full control/configuration

　　Onboard OTP programming supply and control

　　Onboard PMIC control through the I2C register map

　　Fully featured programmer through J36 for external device control/programming

　　On board connectors for interfacing with future evaluation/debug tools

　　Compact form factor (4 x 4 inch2)
