The maximum input voltage that can be applied to the LM5118MH/NOPB is 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 55V 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 input voltage should be well-regulated and free from noise.
The maximum output current that the LM5118MH/NOPB can deliver is 1.5A, but it's recommended to operate within the specified output current range of 0.1A to 1.2A for optimal performance and reliability.
To protect the LM5118MH/NOPB from overcurrent and overheating, it's recommended to implement overcurrent protection (OCP) and overtemperature protection (OTP) mechanisms, such as using a current-sensing resistor and a thermal shutdown circuit.
The recommended PCB layout for the LM5118MH/NOPB involves placing the input capacitor close to the VIN pin, the output capacitor close to the VOUT pin, and the feedback resistors close to the FB pin. Additionally, it's essential to minimize the loop area and use a solid ground plane to reduce noise and electromagnetic interference (EMI).
