Infineon Technologies OptiMOS™ PD (Power Delivery) MOSFETs

Infineon Technologies OptiMOS™ PD (Power Delivery) MOSFETs are ideal for USB-PD and fast-charger designs, supporting short lead and quick-quote response times. The logic-level MOSFETs in PQFN 3.3mm x 3.3mm and SuperSO8 packages have been optimized for synchronous rectification in charger and adapter 25V to 150V SMPS applications. The logic-level drive provides a low gate threshold voltage (VGS(th)), allowing low- and medium-voltage MOSFETs to be driven from 4.5V or directly from microcontrollers, leading to a lower part count in the application.

Features

Low R_DS(on) in small packages without increasing charges
Highest efficiency and power density designs
Low gate charge (Q_g) reduces switching losses without compromising conduction losses
Lower overall and switching losses
Low reverse-recovery charge (Q_rr) and low output charge (Q_oss)
Low overshoot in synchronous rectification

Logic-level compatibility
Logic-level parts can be fully driven from 4.5V or directly from microcontrollers (slow switching)
Supports high switching frequencies
Less heat generation in the application
Improved figures-of-merit for operation at high switching frequencies
Excellent thermal behavior
