LTC3443EDE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 5.5V, as specified in the Absolute Maximum Ratings section of the datasheet. Exceeding this voltage can damage the device.
-
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, as specified in the datasheet. Additionally, the output voltage should be decoupled from the input voltage using a 1uF or larger capacitor.
-
The SS pin is the soft-start pin, which allows the output voltage to ramp up slowly during startup to prevent inrush currents. To use the SS pin, connect a capacitor from the SS pin to GND, and the device will slowly ramp up the output voltage during startup. The value of the capacitor determines the soft-start time.
-
The LTC3443EDE is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
-
The power dissipation of the LTC3443EDE can be calculated using the formula: Pd = (VIN x IIN) + (VOUT x IOUT) + (VIN x IQ), where Pd is the power dissipation, VIN is the input voltage, IIN is the input current, VOUT is the output voltage, IOUT is the output current, and IQ is the quiescent current.
