LT8310IFE#PBF

Power Supply Controllers, Monitors Overview

The LT8310IFE#PBF is a high-voltage forward converter controller manufactured by Analog Devices Inc. It operates with an input voltage range up to 100V and supports a switching frequency of 500 kHz. The device features a maximum duty cycle of 82% and includes a shutdown function for power management. It is housed in a 20-lead TSSOP package with exposed pad, suitable for surface mount applications. The component functions within a temperature range of -40°C to +125°C and draws a typical supply current of 3.8 mA.

Power Supply Controllers, Monitors Feature Summary

• Supports high-voltage forward converter topologies with input voltages up to 100V
• Integrates a fixed 500 kHz switching frequency for efficient power conversion
• Includes a dedicated shutdown pin for precise power control and energy saving

Power Supply Controllers, Monitors Applications

• Industrial power supplies requiring isolated forward conversion
• Telecommunications equipment power stages
• High-voltage DC-DC conversion systems

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the lead frame material and RoHS compliance status through the official datasheet before integration. Ensure the supplier provides traceability documentation consistent with Analog Devices manufacturing standards for quality assurance purposes.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring a dedicated forward converter controller rather than an integrated switcher. The 100V input capability suits higher voltage bus architectures. Consider the thermal performance of the TSSOP-20 package with exposed pad for heat dissipation requirements in dense PCB layouts.

Power Supply Controllers, Monitors Part Context

This part belongs to the LT8310 series of high-voltage switching controllers. It is designed specifically for forward converter applications, distinguishing it from flyback or buck-boost variants within the broader Analog Devices portfolio. The device complements other PMIC solutions by offering discrete control flexibility for custom transformer designs.

Power Supply Controllers, Monitors Replacement Considerations

LT8310EFE#TRPBF offers identical electrical specifications but utilizes tape-and-reel packaging instead of tubes.
