Product Introduction

Overview

The ADP5024ACPZ-R2, produced by Analog Devices Inc., is a highly integrated power management IC that combines two high-performance buck regulators and one low dropout (LDO) regulator. This device is designed to meet the demanding performance and board space requirements of modern electronic systems. It is packaged in a small, 24-lead, 4 mm × 4 mm Lead Frame Chip Scale Package (LFCSP) and operates over a temperature range of −40°C to +125°C.

Key Features

  • Two high-performance buck regulators with adjustable output voltages from 0.8 V to 3.8 V.
  • One low dropout (LDO) regulator with an output voltage range from 0.8 V to 5.2 V.
  • High switching frequency of up to 3 MHz, enabling the use of tiny multilayer external components and minimizing board space.
  • Forced PWM and automatic PWM/PSM modes for efficient operation across various load conditions.
  • Low quiescent current, low dropout voltage, and high power supply rejection ratio (PSRR) to extend battery life in portable devices.
  • Buck regulators operate out of phase to reduce input capacitor requirements.

Applications

  • Power for processors, ASICs, FPGAs, and RF chipsets.
  • Portable instrumentation and medical devices.
  • Space-constrained devices where high performance and compact size are critical.

  3. What are the output voltage ranges for the buck regulators and LDO?
    The buck regulators have an output voltage range from 0.8 V to 3.8 V, and the LDO has an output voltage range from 0.8 V to 5.2 V.
  4. What is the maximum current for each buck regulator and the LDO?
    The maximum current for each buck regulator is 1.2 A, and for the LDO, it is 300 mA.
  5. What is the switching frequency of the buck regulators?
    The switching frequency is up to 3 MHz.
  6. How do the buck regulators operate in terms of PWM and PSM modes?
    The buck regulators operate in forced PWM mode when the MODE pin is set high and in automatic PWM/PSM modes when the load current falls below a predefined threshold.
  7. What is the package type and size of the ADP5024ACPZ-R2?
    The package type is LFCSP (CP-24-10), and the size is 4 mm × 4 mm.
  8. What is the difference between the ADP5024ACPZ-R2 and ADP5024ACPZ-R7?
    The difference is in the packing quantity; the '-R2' comes in a reel of 250 units, and the '-R7' comes in a reel of 1500 units.
  9. What type of capacitors are recommended for use with the ADP5024ACPZ-R2?
    X7R- and X5R-type capacitors are recommended due to their better temperature and dc bias characteristics.
  10. How does the ADP5024ACPZ-R2 help in reducing board space?
    The high switching frequency and out-of-phase operation of the buck regulators reduce the input capacitor requirements, allowing for the use of smaller external components and minimizing board space.
