Infineon Adds a Device to its EiceDRIVER 1EDN TDI Family

Infineon Technologies adds a device to its cost-effective and compact-size EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences.

Infineon The new device (1EDN7550U) is housed in an ultrasmall (1.5 mm x 1.1 mm x 0.39 mm) 6-pin leadless TSNP package. Infineon’s gate-driver ICs with TDIs are key to high-power-density and high-efficiency designs at a lower system cost compared to alternative solutions.

The TSNP package (1EDN7550U) occupies a PCB-area five times smaller compared to its SOT-23 family members. With a 3.3 V PWM input signal at application level, the EiceDRIVER 1EDN TDI can withstand static ground-shifts of up to ± 70 V and transient ground shifts of as much as ± 150 V peak. The combination of tiny size and ground-shift robustness enables two of these gate-driver ICs to operate in a 48 V half-bridge configuration. Concurrently, designers have the freedom to place these gate-driver ICs in the PCB layout wherever they fit best which is key to enabling industry leading power density.

First customers, such as Flex Power Modules, welcome the new TSNP package: ‘The 1EDN7550U driver offers significant board-area savings, which together with its versatility makes it a very attractive part’, said Mikael Appelberg, Chief Technology Officer at Flex Power Modules.

The EiceDRIVER 1EDN7550U, in leadless TSNP package, enables  25 V and 40 V OptiMOS MOSFETs to operate in switched capacitor topologies at 1.2 MHz switching frequency. In such an application, a high power density of 3060 W/in 3 and a 97.1 % peak efficiency (including auxiliary losses) have proven to be possible.
