Frequently Asked Questions
What input voltage range does the LT4320HDD#PBF support, and how does it improve rectifier efficiency?
The LT4320HDD#PBF operates over a 9 V to 72 V input range and drives 4 external N-channel MOSFETs as a full-wave ideal diode bridge, reducing forward conduction losses from roughly 1 V per diode to only a few millivolts, significantly improving rectifier efficiency in AC-DC conversion designs.
Which package does the LT4320HDD#PBF use, and how does it handle thermal dissipation on a PCB?
The LT4320HDD#PBF is housed in an 8-pin SOIC package with an integrated exposed heat sink slug on the bottom, enabling direct thermal coupling to the PCB ground plane. This package measures approximately 5 mm x 5 mm and supports improved thermal dissipation compared to a standard 8-pin SOIC without a slug.
When is the LT4320HDD#PBF a better choice than a Schottky diode bridge in a power supply design?
The LT4320HDD#PBF outperforms Schottky diode bridges in designs where input currents exceed 1 A and power efficiency is critical, since its MOSFET-based approach can reduce bridge rectifier losses by over 90% compared to Schottky diodes with 0.3 V to 0.5 V forward drops. It is particularly advantageous in 48 V industrial or telecom supplies needing compact, high-efficiency AC-DC conversion.
