LTM4638IY#PBF Frequently Asked Questions (FAQ)

  • The maximum operating temperature range for the LTM4638IY#PBF is -40°C to 125°C.

  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled from the input voltage using a capacitor with a value of at least 10uF.

  • The recommended input capacitor value for the LTM4638IY#PBF is 10uF to 22uF, with a voltage rating of at least 2 times the maximum input voltage.

  • The output voltage of the LTM4638IY#PBF can be calculated using the following formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage (typically 0.8V).

  • The maximum input voltage for the LTM4638IY#PBF is 15V.
