Overview
| Topology | Boost Converter |
| Input voltage | 6-20 V |
| Output 1 | 24 V / 3 A |
Description
The EVAL-LT8342-AZ evaluation board provides a proven design to evaluate the LT8342, a 40V, 9A, Low IQ Synchronous Step-Up Silent Switcher™ with Input Disconnect and PassThru™. The application circuit is configured to demonstrate optimum performance and component size. Using the board layout example, optimized for Electromagnetic Interference (EMI), and thermal performance, will help ensure the designer sees similar performance in their system.The evaluation board is configured to run at 2MHz with a 24V output voltage from an input voltage range of 6V to 20V and deliver up to 3A load current when VIN is 12V.
