ChargerLab: Teardown of Realme 50W Mini SuperDart Charger

OPPO’s 50W Mini is a true next-generation GaN fast charger using the latest high-speed topology and enabled by GaNFast Power ICs. A ‘pulsed’ power conversion topology achieves the world’s smallest and thinnest form-factor. Measuring only 82.2 x 39.0 x 10.5 mm (34 cc) and only 60 g in weight, the 50W Mini charges 3x faster than competitors in half the size and weight.

Navitas’ GaNFast power ICs monolithically integrated with GaN logic and GaN analog circuits on a single GaN chip to form a true GaN power IC. These ‘digital-in power-out’ building blocks – known as GaNFast™ power ICs – deliver robust, high-efficiency performance up to 2 MHz. For the Mini, two NV6115 GaNFast power ICs in speed-optimized, surface-mount QFN packages are used.
