Description

Avago's 2.5 Amp Automotive R2Coupler Gate Drive Op-

tocoupler contains an AlGaAs LED, which is optically cou-

pled to an integrated circuit with a power output stage.

The ACPL-K34T features fast propagation delay and tight

timing skew, is ideally designed for driving power MOS-

FETs used in AC-DC and DC-DC converters. The high oper-

ating voltage range of the output stage provides the drive

voltages required by gate controlled devices. The voltage

and high peak output current supplied by this optocou-

pler make it ideally suited for direct driving power MOS-

FETs at high frequency for high efficiency conversion.

Avago R2Coupler isolation products provide reinforced

insulation and reliability that delivers safe signal isolation

critical in automotive and high temperature industrial ap-

plications.
