ADPL16000AATA+T

Voltage Regulators - DC DC Switching Regulators Overview

The ADPL16000AATA+T is a high-efficiency, high-voltage synchronous DC-DC buck converter from Analog Devices. It integrates power MOSFETs and operates within a wide input voltage range of 4.5V to 60V. The device delivers up to 400mA of load current with a fixed 3.3V output. It utilizes peak current mode control architecture and features a MODE pin for selecting between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) operation modes. The component is housed in a compact 8-pin, 2mm x 2mm TDFN-CU package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates internal MOSFETs and compensation circuitry to minimize external component count and reduce total system cost.
• Supports flexible power rail configurations through selectable PWM or PFM control modes via the MODE pin.
• Includes built-in overvoltage monitoring with an open-drain reset pin and programmable enable/UVLO thresholds.
• Ensures reliable operation in harsh industrial environments with features like hiccup-mode current limiting and auto-retry startup.

Voltage Regulators - DC DC Switching Regulators Applications

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

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AATA' against the official Analog Devices datasheet to confirm the fixed 3.3V output variant and tape-and-reel packaging configuration. Ensure compatibility with the required thermal dissipation characteristics for the TDFN-CU package in your target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside high efficiency in a small footprint. The integrated design simplifies layout compared to discrete solutions. Consider the PFM mode for improved light-load efficiency if standby power consumption is a critical design constraint.
