Bi-Directional
Power ICs with Dual-Channel Isolated GaN Driver
GaNSlim™ is the next generation of Navitas’ GaNSense™ family. It offers the simplest, easiest, and fastest system design by integrating drive, control and protection, with autonomous EMI control and lossless current-sensing, all within a 4-pin, high thermal performance industry standard package. Target applications include chargers for mobile devices and laptops, TV power supplies, lighting systems, and other devices with power requirements of up to 500 W.

• XX% efficient
• XX W/in3 density
• $XX/W system cost
Latest Two-Stage with GaN/SiC

• YY% efficient
• YY W/in3 density
• $YY/W system cost
• 20-30% energy savings
• 20-30% higher density
• 0-20% more expensive
New Single-Stage with
Bi-Directional GaN/SiC

• Eliminates PFC stage
• Eliminates DC Link capacitors
• Enables ultra-high frequencies
• Add’l 30% density, size and weight
• Add’l 10% energy savings
• 0-10% less expensive
• 30% higher GaN/SiC content
Applications
Bi-Directional GaNFast advances topologies by directly converting AC input voltage into a corrected & controlled AC or DC output voltage.

Monolithically integrated active substrate clamp (ASC)
Navitas patented ASC automatically connects each Source to the common substrate, eliminating a ‘back-gating’ effect, which prevents an undesired increase in RSS(ON) when the substrate potential is uncontrolled. This results in a stable RSS(ON) for highest performance, efficiency, & reliability

Automatically detects and connects alternative Sources to Substrate for highest performance, efficiency & reliability

65% lower RSS(on) (clamped) / 20% cooler!
