Overview
The LT8302IS8E#PBF is a flyback switching regulator from Analog Devices, designed for isolated power conversion. It operates with an input voltage range of 2.8 V to 42 V and delivers up to 3.6 A switch current at a maximum output voltage of 65 V. The device features a low quiescent current of 380 uA and supports a switch frequency adjustable down to 12.7 kHz. It is housed in an 8-SOIC package with an exposed pad (SOIC-Narrow-EP-8) and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrated high-voltage startup circuit enables operation from low input voltages without external bias supplies.
- Capable of generating positive or negative isolated outputs using a single transformer winding.
- Supports remote sense functionality to maintain accurate output voltage regulation under varying load conditions.
Applications
- Industrial isolated DC-DC conversion
- Battery-powered equipment requiring isolation
- Telecommunications power systems
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and thermal rating. Confirm that the component meets required environmental standards such as RoHS compliance. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability documents for quality assurance purposes.
Selection Notes
Select this component when designing isolated flyback converters requiring wide input ranges and high output currents. Consider the SOIC-Narrow-EP-8 package for thermal management needs. Evaluate the need for remote sensing capabilities to compensate for voltage drops in long traces. Verify compatibility with available passive components for the desired switching frequency.
Part Context
This part belongs to the LT8302 family of ultra-low IQ flyback controllers. It shares core architecture with variants like LT8302IS8E-3#PBF but differs in packaging and specific electrical characteristics. The series is designed for applications demanding high efficiency and minimal standby power consumption.
Replacement Considerations
LT8302IS8E-3#PBF is a related variant within the same product family. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative part meets the same thermal and environmental operating requirements.
