ADPL16000BATA+T

Overview

The ADPL16000BATA+T is a high-voltage synchronous step-down DC-DC converter from Analog Devices Inc., integrating internal MOSFETs for efficient power conversion. It operates within a wide input voltage range of 4.5V to 60V and delivers up to 400mA of load current. This specific variant provides a fixed 5V output voltage, suitable for applications requiring stable low-voltage rails from higher input sources. The device utilizes peak current mode control architecture with a MODE pin to select between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) operations, optimizing efficiency across varying load conditions. It features internal compensation, feedback dividers, and soft-start capabilities, allowing for minimal external component usage. Packaged in a compact 8-pin 2mm x 2mm TDFN-CU format, it supports flexible system design while maintaining reliability in harsh industrial environments.

Feature Summary

• Integrated synchronous rectification eliminates the need for external Schottky diodes, reducing component count and enhancing overall conversion efficiency.
• Configurable switching modes allow selection between PWM for constant frequency operation and PFM for improved light-load efficiency.
• Built-in protection mechanisms include over-temperature shutdown, current limit with auto-retry startup, and monotonic startup for pre-biased outputs.
• Internal compensation and fixed feedback networks simplify circuit design by minimizing the requirement for external passive components.

Applications

• Industrial sensor power supplies
• HVAC and building control systems
• High-voltage LDO replacement circuits
• General-purpose point-of-load (POL) regulation

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm the fixed 5V output configuration and tape-and-reel packaging status. Ensure compatibility with the specified 8-pin TDFN-CU footprint during PCB layout. Cross-reference the datasheet for thermal performance requirements under maximum load conditions to validate heatsinking needs. Confirm RoHS compliance and environmental ratings match project specifications before finalizing procurement orders.

Selection Notes
