Dual-channel junction-isolated gate driver | EiceDRIVER™ 2EDL8
Dual-channel junction-isolated gate driver | EiceDRIVER™ 2EDL8
Designed for medium-voltage power MOSFETs in half-bridge applications such as telecom and datacom DC-DC converters, Infineon introduces the EiceDRIVER™ 2EDL8 family of dual-channel junction-isolated gate driver ICs.
Designers can choose between two different pull-up currents: The 3 A version can be the right choice for retrofit designs. The industry-leading 4 A version is recommended to reduce MOSFET switching losses.
The 2EDL8 family will be available with two different input configurations: The 2EDL802x permits operation of both channels independently. For this reason, it is the perfect choice for diagonally driven full-bridges on the primary side as well as for the synchronous rectification stage on the secondary side because it permits reduction of losses during the free-wheeling phase. The differential input structure of the 2EDL812x effectively renders it to be a half-bridge gate driver with built-in shoot-through protection, making it a good choice for the primary-side half-bridge stages in DC-to-DC brick converters.
The 2EDL8xxx products come in an industry-standard leadless package and pin-out. All of them have an integrated 120 V boot-strap diode as well as a precise channel-to-channel propagation delay matching of +/- 2 ns.
