Overview
The LT3582EUD-5#PBF is a dual DC/DC converter from Analog Devices, featuring a boost and a single inductor inverting topology. It provides fixed positive and negative outputs of +5V and -5V respectively. The device operates with an input voltage range of 2.475 V to 5.5 V. Key electrical specifications include a maximum output current of 200 mA per channel, a quiescent current of 325 uA, and a switching frequency of 100 kHz. It is housed in a 16-lead QFN package and supports operation temperatures from -40°C to +125°C.
Feature Summary
- Integrates boost and inverting converters using a single external inductor for space efficiency
- Includes optional I2C programming and one-time programmable memory for configuration flexibility
- Features integrated feedback resistors for simplified circuit design
Applications
- Portable devices requiring simultaneous positive and negative supply rails
- Industrial systems needing isolated or split power supplies from a single source
- Battery-powered equipment utilizing single-inductor dual-output topologies
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the operating temperature range meets your environmental requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact solution for generating both positive and negative voltages from a low-voltage source is required. The single-inductor architecture reduces component count compared to dual-inductor designs. Consider the 100 kHz switching frequency for EMI management and the 325 uA quiescent current for battery life optimization in portable applications.
Part Context
This part belongs to the LT3582 family, which includes variants like the LT3582-12 offering different fixed output voltages. The series is designed for applications requiring efficient power conversion from lithium-ion or similar single-cell batteries. The EUD package denotes a specific thermal and footprint configuration within the QFN family.
Replacement Considerations
The LT3582EUD-12#PBF serves as a functional substitute if a 12V output is acceptable instead of 5V. Verify that the pinout and thermal characteristics remain compatible with the existing PCB layout when considering alternative packages or updated revisions.
