For new designs, NXP® recommends using the MMPF0100 or MC34709
MC34708 is the PMIC designed specifically for use with the NXP i.MX50 and i.MX53 processor families (Mature processors). It is available in a 8x8 and 13x13mm MAPBGA and supports an ambient operating temperature range of -40 to 85 deg. C for various consumer applications. As the companion PMIC on several i.MX reference designs, it is a proven solution, which enables a faster time to market with fewer resources. It integrates six buck and eight LDO regulators to provide power for the processor core, memory and peripherals. A mini/micro USB switch supports USB, UART, and audio inputs to help reduce the connector count for a more compact design. In addition, the MC34708 integrates a real time clock, coin cell charger, 10-bit ADC, 5V boost regulator for USB-OTG support , PWM generator, resistive touch screen interface, general purpose LED drivers and four GPIOs.
