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.
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.
Applications
- Industrial sensor power supplies
- HVAC and building control systems
- High-voltage LDO replacement circuits
- General-purpose point-of-load (POL) conversion
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.
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.
Part Context
This part belongs to the ADPL16000 family of synchronous buck converters designed for robust industrial applications. The family includes variants with different fixed output voltages, such as the ADPL16000B for 5V outputs and the ADPL16000C for adjustable outputs, allowing designers to choose the appropriate version based on specific voltage requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices directly for qualified alternatives or cross-reference options that match the 60V input capability and 400mA current rating.
