Efficient, reliable PMU for complex integrated
power solutions required by advanced software-defined radio and
FPGA applications
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance semiconductors for signal-processing applications,
introduced today an integrated family of efficient power management
ICs (integrated circuits) targeting compact, high density power
solutions for RF agile radio and FPGA/processor-based
(field-programmable gate array) applications.
The ADP505x family of power management ICs 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 Corp.’s (NASDAQ: ALTR) and Xilinx Inc.’s
(NASDAQ: XLNX) FPGA platforms. For more information about ADI
integrated power management solutions and FPGAs: Integrated Power
Solutions for Altera FPGAs and Integrated Power Solutions for
Xilinx FPGAs.

The ADP505x combines multiple buck regulators and LDOs
(low-dropout regulators) into a single, compact 48-lead LFCSP (7 mm
x 7 mm) package resulting in a power density solution of up to 25 W
power design in only 310 mm2 PCB area. It is an extremely 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, increasing the power solution’s
overall reliability. Its integrated design allows a single IC to be
designed into many different applications, reducing power supply
design time.
The ADP5050/51/52/53 two-high current buck regulators are
resistor programmable using an external resistor to allow the power
supply designer to quickly trim the current limit to 4A, 2.5A or
1.2A. All four switching regulators operate over a wide input
voltage range (4.5 V to 15 V) and are synchronized to a single
clock with a wide programmable range (250 kHz to 1.4M Hz), which
have programmable phase shits (0°, 90°, 180°, 270°) on each buck
regulator to reduce input ripple.
