LT4320IDD#PBF

OR Controllers, Ideal Diodes Overview

The LT4320IDD#PBF is an ideal diode bridge controller manufactured by Analog Devices Inc., designed for professional power management applications. It operates within a supply voltage range of 9 V to 72 V and features a typical operating supply current of 1.5 mA. The device supports input currents up to 300 uA and output currents of 1 mA, functioning effectively across temperatures from -40°C to +85°C. Packaged in an 8-DFN (3x3) surface-mount format, it replaces traditional full-wave diode bridge rectifiers with low-loss N-channel MOSFETs to minimize voltage drop and thermal dissipation.

OR Controllers, Ideal Diodes Feature Summary
