LT1935ES5 - Analog Devices

LT1935ES5 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the LT1935ES5?
  The recommended layout and placement for the LT1935ES5 involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. A 4-layer PCB with a solid ground plane is recommended. Refer to the application note AN-72 for more details.
• How do I optimize the compensation network for the LT1935ES5?
  The compensation network for the LT1935ES5 can be optimized by following the guidelines in the datasheet and using the SPICE models provided by Analog Devices. The compensation network should be designed to provide a phase margin of at least 45° and a gain margin of at least 10dB. The values of the compensation components can be adjusted to achieve the desired stability and transient response.
• What is the maximum output current that the LT1935ES5 can deliver?
  The maximum output current that the LT1935ES5 can deliver is 3.5A. However, the output current should be derated based on the ambient temperature and the thermal resistance of the package. Refer to the thermal derating curves in the datasheet for more information.
• Can the LT1935ES5 be used in a high-temperature environment?
  The LT1935ES5 is rated for operation up to 125°C junction temperature. However, the device should be derated for high-temperature operation, and the maximum output current should be reduced accordingly. Refer to the thermal derating curves in the datasheet for more information.
• How do I protect the LT1935ES5 from overvoltage and undervoltage conditions?
  The LT1935ES5 has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection may be required depending on the application. External OVP and UVLO circuits can be added to provide additional protection against voltage transients and faults.
