LT3482 LINER [Linear Technology], LT3482 Datasheet - Page 9

• Manufacturer Part Number: LT3482
• Description: 90V Boost DC/DC Converter with APD Current Monitor
• Manufacturer: LINER [Linear Technology]

In some applications, a long cable or wire is used to connect
the LT3482 to APD. When APD is shorted to GND, APD pin
voltage might ring below ground and damage the internal
circuitry. To prevent damage during short-circuit event, a
20Ω resistor must be added in series with the APD.
