Analog Devices Inc. ADP5024ACPZ-R2

Overview

ADP5024ACPZ-R2 from Analog Devices is a compact three-output PMIC integrating two 1200mA buck regulators and one 300mA low-dropout regulator. The device is designed for portable and embedded systems that require higher buck current than smaller micro-PMU options while maintaining a low-noise LDO rail.

As part of the ADP5024 product family, ADP5024ACPZ-R2 provides dual 3MHz buck regulators, one high-PSRR low-noise LDO, 2.3V to 5.5V main input operation, factory-programmable or adjustable outputs, and a 24-lead 4mm x 4mm LFCSP package. For engineers reviewing the ADP5024ACPZ-R2 datasheet, ADP5024ACPZ-R2 pinout, ADP5024ACPZ-R2 application, or ADP5024ACPZ-R2 equivalent, this device is widely used in portable processors, FPGA support rails, wireless modules, handheld instruments, mixed-signal boards, and compact multi-rail embedded systems.

Technical Context

In embedded processor systems, ADP5024ACPZ-R2 operates as a three-output PMIC where two 1200mA buck regulators supply efficient high-current rails and the LDO regulator supplies a low-noise auxiliary rail.

The 3MHz switching frequency allows small inductors and capacitors, while automatic PWM/PSM behavior and forced PWM options help balance light-load efficiency and noise performance.

ADP5024ACPZ-R2 is useful when two switching rails need more current than the ADP5023 class but the system still benefits from a single integrated LDO for analog or peripheral supply.

Key Specifications

Pinout & Package

The ADP5023ACPZ-1-R7 pinout includes buck input and switch pins, LDO input and output pins, enable pins, feedback or output setting pins, power-good functions, and exposed-pad ground.

For PCB design, each buck inductor and capacitor should be close to the PMIC, LDO capacitors should be placed near the output, and feedback traces should avoid switch-node noise.

Key Features

• Two 800mA buck regulators support efficient system rails.
• 300mA LDO provides low-noise auxiliary power.
• 3MHz switching reduces passive component size.
• Independent enables support sequencing.
• LFCSP package saves PCB area.
• Three-output architecture reduces external regulator count.

Applications

Equivalent & Alternatives

When evaluating a ADP5023ACPZ-1-R7 equivalent, engineers should compare number of outputs, buck current, LDO current, input range, switching frequency, package, and enable behavior.

Compared with ADP5024ACPZ-1-R7, ADP5023ACPZ-1-R7 should be selected when the ADP5023 three-output rail structure and suffix option match the design. ADP5023ACPZ-1-R7 vs ADP2140ACPZ3312R7 selection depends on whether the system needs two buck rails or a simpler buck-plus-LDO solution.

Quality

ADP5023ACPZ-1-R7 should be sourced as original Analog Devices components through traceable channels. Quality checks may include LFCSP package inspection, top-mark validation, solderability testing, and three-output electrical verification.

Production validation should include buck stability, LDO noise, startup sequencing, output accuracy, thermal behavior, and switching-layout review.

Availability

ADP5023ACPZ-1-R7 available at Aetrix Electronics and is suitable for portable, wireless, processor, and mixed-signal embedded systems requiring compact three-output PMIC supply support.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs.
