PMICs for RF agile radios and FPGAs

Power Electronics / Power Management
Analog Devices rolled out an integrated family of efficient power management integrated circuits (PMIC) targeting compact, high-density power solutions for RF agile radio and FPGA/processor-based applications.
The ADP505x family was designed as an integrated power solution for picocell and femtocell base stations, portable and handheld devices as well as most applications needing a compact, integrated power solution. Designed to support Analog Devices’ AD9361 RF transceiver for software-defined radio (SDR) applications, it can also be used as an integrated power solution for many of Altera’s and Xilinx’s FPGA platforms.
The chips combine multiple buck regulators and LDOs (low-dropout regulators) into a single, compact 48-lead LFCSP (7 x 7 mm) package resulting in a power density solution of up to 25 W in a 310 mm² PCB area. It is a highly versatile multi-output regulator with four buck switching regulators (4 A, 4 A, 1,2 A, 1,2 A) and one 200 mA LDO.
The ADP5050 implements an I²C interface that allows the input voltage to the device and the die temperature to be monitored. The ADP5050/51/52/53 high-current buck regulators are resistor programmable using an external resistor to allow the power supply designer to quickly trim the current limit to 4 A, 2,5 A or 1,2 A.
All four switching regulators operate over a wide input voltage range (4,5 V to 15 V) and are synchronised to a single clock with a wide programmable range (250 kHz to 1,4 MHz) with programmable phase shifts (0°, 90°, 180°, 270°) on each buck regulator to reduce input ripple.
