Overview
The LT3582EUD-12#PBF is an I2C programmable dual-channel DC/DC converter manufactured by Analog Devices Inc. It integrates a boost converter and a single-inductor inverting converter within a QFN-16 package. The device provides two outputs, including a fixed 12 V positive output and a negative rail, with a maximum output current of 200 mA. Operating from an input voltage range of 2.475 V to 5.5 V, it features a switching frequency of 100 kHz and a typical quiescent current of 325 uA. The component supports operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrates a boost converter and a single-inductor inverting topology for simultaneous positive and negative generation.
- Features I2C programmability for flexible configuration of operating parameters.
- Includes shutdown functionality to minimize power consumption during inactive states.
Applications
- Active matrix OLED display biasing
- CCD (Charge Coupled Device) applications
- General purpose bias circuits requiring both positive and negative rails
Procurement Notes
Verify availability status carefully as the part may be subject to limited supply or factory special order conditions. Confirm that the specific suffix matches the required performance specifications and packaging format before finalizing procurement plans. Ensure compatibility with existing design constraints regarding thermal management and interface requirements.
Selection Notes
Select this component when a compact solution is needed to generate both positive and negative voltages from a single inductor. The I2C interface allows for dynamic adjustment, making it suitable for systems requiring programmable power rails. Consider the 200 mA output capability and 100 kHz switching frequency against system efficiency and size requirements.
Part Context
This part belongs to the LT3582 series of dual-channel DC/DC converters designed for applications requiring multiple power rails. It is distinct from other LT3582 variants such as the LT3582-5, which provides different fixed output voltages. The EUD-12 suffix indicates the specific package type and the 12 V output configuration.
Replacement Considerations
LT3582EUD-5#PBF offers similar functionality with a 5 V output instead of 12 V. LT3582EUD#PBF provides adjustable output options rather than a fixed 12 V rail. Verify pinout and electrical characteristics match before substituting.
