6.3 Functional Description
The MC34708 Power Management Integrated Circuit (PMIC) represents a complete system power solution in a single package.
Designed specifically for use with the Freescale i.MX50/53 families. The MC34708 integrates six multi-mode buck regulators and
eight LDO regulators for direct supply of the processor core, memory and peripherals.
The USB switch enables the use of a single, mini or micro USB connector for USB, UART and audio connections, switching the
relevant signals to the connector depending on the type of device connected. In addition, the MC34708 also integrates a real
time clock, coin cell charger, a 13-channel 10-bit ADC, 5
V USB Boost regulator, two PWM outputs, touch-screen interface, status
LED drivers and four GPIOs.
