Overview
The ADP5055ACCZ-R7 is a triple high-current buck regulator from Analog Devices, housed in an LGA-43 package. It operates with an input voltage range of 2.75 V to 18 V and delivers up to 7 A output current. The device features a fixed switching frequency of 600 kHz and supports output voltages including 1.2 V, 1.8 V, 2.5 V, and 3.3 V. It functions within a temperature range of -40°C to +150°C and draws 6.2 mA of static current.
Feature Summary
- Integrates three independent high-current synchronous buck converters for multi-rail power distribution.
- Supports wide input voltage ranges suitable for industrial and automotive bus architectures.
- Includes integrated shutdown functionality for system power management.
Applications
- Industrial equipment requiring multiple regulated voltage rails
- Automotive infotainment and control systems
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix ACCZ-R7 against the manufacturer datasheet to confirm pinout and thermal specifications. Ensure the LGA-43 footprint matches the PCB layout requirements. Confirm RoHS compliance status through official documentation before integration.
Selection Notes
Select this component when designing systems requiring three isolated high-current outputs from a single wide-input source. Evaluate thermal performance at maximum load conditions due to the high current capability. Compare against single-channel regulators if fewer outputs are sufficient to reduce board space.
Part Context
This part belongs to the ADP5055 family of integrated power management solutions designed for complex electronic systems. It consolidates multiple power stages into a single compact package, reducing component count compared to discrete solutions. The series targets applications demanding high efficiency and reliability in constrained spaces.
Replacement Considerations
Consult official Analog Devices documentation for verified cross-reference part numbers. Do not substitute based on generic pin compatibility without verifying electrical parameters and thermal characteristics.
