Compact GaN driver cuts power supply size by up to 80%
The LMG1020 gallium nitride (GaN) driver from Texas Instruments is available from Mouser Electronics. The single, low-side driver enables efficient, high-performance designs in speed-critical applications such as LiDAR, time-of-flight laser drivers, facial recognition, augmented reality, and class E wireless chargers.
The device drives GaN FETs and logic-level MOFSETs, enabling propagation delays of just 2.5 nanoseconds and minimum pulse width of 1 nanosecond.
Its drive strength is independently adjustable for pull-up and pull-down edges by connecting external resistors between the gate and OUTH and OUTL, respectively.
Robust, the driver features over-temperature protection and under-voltage lockout to guard against overload and fault conditions, plus common-mode transient immunity of more than 300V/ns, delivering industry-leading system-noise immunity.
It is housed in a 0.8mm × 1.2mm WCSP package, which minimises gate loop inductance and maximises power density in high-frequency applications. The miniscule size allows designers to reduce component count and decrease power supply size by up to 80%.
The LMG1020 driver features an adjustable dead-time control feature to provide improved efficiency for applications such as DC-DC converters, Class D audio amplifiers, and motor drives.
