Overview
The LT8304ES8E#PBF is a high-voltage isolated flyback converter from Analog Devices, designed for ultra-low quiescent current operation. It supports an input voltage range of 3 V to 100 V and delivers up to 2 A output current with a maximum output voltage of 150 V. The device operates at a switching frequency of 350 kHz and features a static current of 390 uA. It is housed in an SOIC-Narrow-EP-8 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low quiescent current consumption for efficient standby operation
- Integrated high-voltage switch eliminates external MOSFET requirements
- No-opto isolation capability reduces component count and cost
- Wide input voltage range accommodates various power sources
Applications
- Industrial isolated DC-DC conversion
- Battery-powered equipment with high-voltage isolation needs
- Medical equipment power supplies
- Sensor interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix ES8E#PBF against official Analog Devices documentation to confirm pinout, thermal pad configuration, and RoHS compliance status. Ensure the ordering part number matches the required package variant and lead-free specifications before procurement. Cross-reference with the manufacturer's latest datasheet to validate availability and any recent product change notifications affecting this specific revision.
Selection Notes
Select this component when designing isolated flyback converters requiring minimal standby power consumption. It is suitable for applications needing wide input voltage ranges up to 100 V without external switching transistors. Consider the 350 kHz switching frequency for balancing efficiency and passive component size. Ensure the design accounts for the SOIC-Narrow-EP-8 package thermal characteristics for reliable operation at higher loads.
Part Context
The LT8304 belongs to Analog Devices' family of high-voltage isolated flyback converters. It integrates a high-voltage switch and controller into a single package, simplifying the design of isolated power supplies. This series is characterized by low quiescent current and no-opto regulation capabilities, making it distinct from traditional isolated converter designs that require optocouplers and external feedback networks.
Replacement Considerations
Consult Analog Devices documentation for direct replacements or pin-compatible alternatives within the LT830x series. Verify electrical parameters such as input voltage range, output current capability, and switching frequency when substituting with other models. Ensure thermal performance and package compatibility are maintained if replacing with devices from different manufacturers.
