Infineon Technologies Launches New Gate Driver IC for 5G and LTE Macro Base Stations
Infineon Technologies AG introduces the new EiceDRIVER™ 2EDL8 gate driver IC product family to meet the growing demand for DC-DC telecom bricks for mobile network infrastructure equipment. These dual-channel junction-isolated gate driver ICs provide high power density , high efficiency and ruggedness for isolated DC-DC step-down converters/telecom bricks to help build macro base stations for 5G and LTE telecom infrastructure equipment.
Four versions
The new 2EDL8 family includes four versions with two different pull-up currents and two different input configurations: a 3A version for retrofit designs and an industry-leading 4A version for reduced MOSFET switching losses.
Dual Channel
The 2EDL802x dual channels can operate independently, making them ideal for driving diagonally full-bridges on the primary side and synchronous rectification stages on the secondary side to reduce freewheeling losses. The 2EDL812x uses a differential input structure and built-in shoot-through protection, making it a perfect choice for driving off-diagonally primary half-bridge stages in DC-DC brick converters.
Standards compliant
The 2EDL8 features an integrated 120V bootstrap diode and precise channel-to-channel propagation delay matching (± 2 ns typical). All products in this series are available in the industry-standard PG-VDSON-8 leadless package and pinout.
