DC2062AF DEMO MANUAL DC2062A introduces the LT®4363 surge stopper in a 12V, 3A ISO-7637-2 application.
This document provides instructions for using the DC2062A demonstration circuit, which features the LT4363 surge stopper to protect 12V systems from voltage spikes and load dumps. It includes setup procedures, component details, and compliance testing information.
The board regulates output voltage to 25V and limits input to 50V, with protection against reverse voltage up to -150V. It includes test points and LEDs for monitoring operation and fault conditions.
| Input Supply Operating | 5 to 23.5 V DC |
|---|
The maximum input voltage is limited to 50V DC.
The DC2062A suppresses 100V load dump pulses and regulates output voltage to 25V, with components rated for power dissipation during the event.
The output shuts off and LED1 extinguishes until the input voltage drops below 20V.
For DC2062A-A, reset by pulling SHDN low for at least 100μs. For DC2062A-B, it automatically retries after a 22.8s cool-down.
