Tiny Integrated Solution Powers RF Agile Radio Applications and FPGAs
Efficient, reliable PMU for complex integrated power solutions required by advanced software-defined radio and FPGA 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

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.
