Analog Devices LT8418 | Demoboard EVAL-LT8418-AZ
100V Half-Bridge GaN Driver with Smart Integrated Bootstrap Switch
Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 80 V |
| Switching frequency | 100-10000 kHz |
| Output 1 | 80 V / 10 A |
Description
The EVAL-LT8418-AZ evaluation circuit features the LT8418 driving two 100V enhanced Gallium Nitride (eGaN) FETs in a half-bridge configuration. The circuit is optimized as a buck converter, but it can be used as a boost converter or other converter topologies consisting of a half-bridge. The evaluation circuit can deliver up to 10A with good thermal management.
Features
Half-Bridge Gate Driver for GaN FETs
0.6Ω Pull-Up Resistance at Top Gate Driver
0.2Ω Pull-Down Resistance at Bottom Gate Driver
4A Peak Source, 8A Peak Sink Current Capability
Smart Integrated Bootstrap Switch
Split-Gate-Driver to Adjust Turn-On/Turn-Off Strength
Default Low-State for All Driver Inputs and Outputs
Maximum 15V Voltage Rating at INT and INB Inputs
Independent INT, INB Inputs with TTL Logic Compatible
Fast Propagation Delay: 10ns (Typical)
Propagation Delay Matching: 1.5ns (Typical)
Balanced Driver Supply Voltage: VBST ≈ VCC = 3.85V – 5.5V
Undervoltage and Overvoltage Lockout Protections
Small 12-Ball WLCSP Package
Typical applications
