March 5, 2014 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced a family of high-efficiency power management ICs for small, high-density power solutions for RF high-speed wireless and field-programmable gate array (FPGA) processor-based applications.

The ADP505x power management IC family is designed for picocell and femtocell base stations, portable devices, and all applications requiring small, integrated power solutions. Additionally, the ADP505x family is designed to support Analog Devices’ AD9361 RF transceiver for Software Defined Radio (SDR) applications and can be used as an integrated power solution on various Altera and Xilinx FPGA platforms. Further information on Analog Devices’ integrated power management solutions and FPGAs can be found in Integrated Power Solutions for Altera FPGAs and Integrated Power Solutions for Xilinx FPGAs.

The ADP505x integrates multiple buck regulators and low-dropout regulators (LDOs) into a single package of a small 48-lead LFCSP (7 mm x 7 mm), providing a power density solution of up to 25W in a PCB area of only 310 mm². It is a very useful multi-output regulator with four buck switching regulators (4A, 4A, 1.2A, 1.2A) and one 200mA LDO. The ADP5050 implements an I²C® interface that monitors the device's input voltage and die temperature to improve the overall reliability of power solutions. Thanks to this integrated design, the single ADP5050 IC enables system designers to reduce power supply design time across various applications.

The two high-current buck regulators of the ADP5050/51/52/53 can be programmed using external resistors to allow power supply designers to quickly trim the current limit to 4A, 2.5A, or 1.2A. Additionally, all four switching regulators operate over a wide input voltage range (4.5V to 15V), and can be programmed with phase shifts (0°, 90°, 180°, 270°) to minimize input ripple of each buck regulator through single-clock synchronization, and can be programmed with a wide switching range (250kHz to 1.4MHz).
