Overview
The ADP8140ACPZ-1-R7 is a four-channel high-current LED driver IC from Analog Devices, designed for industrial white LED control. It operates with an input voltage range of 3 V to 30 V and supports a buck topology. Each channel can sink up to 500 mA, with the current programmed via a single external resistor. The device features PWM dimming and open LED protection, operating within a temperature range of -40°C to +125°C in a 16-pin LFCSP package.
Feature Summary
- Provides high-current control for up to four independent LED channels
- Supports PWM dimming for precise brightness adjustment
- Includes integrated open LED protection circuitry
- Allows global current programming using a single external resistor
Applications
- Industrial high-brightness white LED control systems
- LED drivers utilizing buck power stages
- LED drivers utilizing boost power stages
- LED drivers utilizing PMOS regulation stages
- LED drivers utilizing shunt regulators
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required pinout and electrical characteristics. Check for moisture sensitivity level requirements during storage and handling. Ensure the supply chain provides valid traceability documentation. Validate that the part number corresponds to the exact functional specification needed for the design.
Selection Notes
Select this component when designing circuits requiring independent control of multiple high-current LEDs. It is suitable for applications needing a wide input voltage range up to 30 V. Consider the thermal performance of the LFCSP package for high-density designs. Ensure the external components support the desired switching frequency and current levels. Verify compatibility with the chosen power stage topology.
Part Context
This part belongs to the ADP8140 series of LED lighting drivers. It is distinct from other Analog Devices PMICs like the ADP1740 LDO or ADP2441 switcher. The series focuses on multi-channel LED control rather than general voltage regulation. It shares the manufacturer's focus on industrial-grade reliability and precision control capabilities.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or cross-references.
