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.

Single-stage topology advantage

Over 70% (?) of Power Semis are used in Two-Stage Converters

Traditional Two-Stage with Si

• 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.

Motor Drives
(Matrix Inverter)

Single Stage OBC
(NPC-T / H4 PFC/ Vienna)

Solar Microinverter
(Cyclo / HERIC)

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!
