PAC5220
Power Application Controller
1. GENERAL DESCRIPTION
The PAC5220 belongs to Active-Semi's broad portfolio of full-featured Power Application Controller^TM (PAC)
products that are highly optimized for controlling and powering next generation smart energy appliances,
devices, and equipment. These application controllers integrate a 50MHz ARM^® Cortex^TM-M0 32-bit
microcontroller core with Active-Semi's proprietary and patent-pending Multi-Mode Power Manager^TM,
Configurable Analog Front End^TM, and Application Specific Power Drivers^TM to form the most compact
microcontroller-based power and general purpose application systems ranging from digital power supply to
motor control. The PAC5220 microcontroller features up to 32kB of embedded FLASH and 8kB of SRAM
memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers,
5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
The Multi-Mode Power Manager (MMPM) provides “all-in-one” efficient power management solution for multiple
types of power sources. It features a configurable multi-mode switching supply controller capable of operating in
buck, flyback, or boost mode, and up to four linear regulated voltage supplies. The Application Specific Power
Drivers (ASPD) are high-voltage power drivers designed for each target set of control applications, including half
bridge, H-bridge, 3-phase, intelligent power module (IPM), and general purpose driving. The Configurable
Analog Front End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable
gain amplifiers, comparators, digital-to-analog converters, and I/Os for programmable and inter-connectible
signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals. Together, these
modules and microcontroller enable a wide range of compact applications with highly integrated power
management, driving, feedback, and control for DC supply up to 52V and for line AC supply.
