The maximum input voltage that can be applied to the LT1787HVCMS8 is 80V, but it's recommended to operate within the specified input voltage range of 4.5V to 60V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor, input capacitor, and feedback resistors. Additionally, the output voltage should be decoupled from the input voltage using a capacitor to prevent oscillations.
The maximum output current that the LT1787HVCMS8 can deliver is 2A, but it's limited by the thermal dissipation and the input voltage. The output current should be derated based on the ambient temperature and the input voltage to ensure reliable operation.
The LT1787HVCMS8 has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be achieved by using external components such as zener diodes, TVS diodes, or voltage supervisors to detect and respond to overvoltage and undervoltage conditions.
The typical startup time of the LT1787HVCMS8 is around 1ms, but it can vary depending on the input voltage, output voltage, and the external components used. The startup time can be affected by the soft-start feature, which can be adjusted using an external capacitor.
