- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.

Vin Connection (Pin 3)
- Connected through net
- Analysis: The LTC3401 can operate with an input range of 0.5V to 5.5V[1]. Ensure the provided VIN falls within this range. Also, considering the inductor and capacitor are connected correctly, this setup appears to be standard for power input smoothing and supply decoupling.
-
VOUT (Pin 7)
- Connected through net
- Analysis: This connection supports the output voltage distribution. Ensure the output requirements align with the capabilities of the LTC3401 and the needs of connected devices, especially since the LTC3401 can efficiently convert voltages with high efficiency[2]. Check connected components to confirm compatibility with the output voltage.
-
Ground (GND, Pin 5)
- Connected to
- Analysis: Ground connections are crucial for the common return path and noise reduction. This seems correctly implemented.
-
FB (Feedback, Pin 8)
- Connected with
- Analysis: The feedback network using R17 and R19 is critical for regulating the output voltage. The values of these resistors determine the output voltage as per the LTC3401's feedback mechanism. Ensure these values are correctly calculated to achieve the desired VOUT, based on the formula provided in the LTC3401 datasheet or application notes.
-
Switching Node (SW, Pin 4)
- Connected to
- Analysis: The connection with the Schottky diode (D3) and inductor (L2) is a part of the standard configuration for a boost converter. Verify the current rating of D3 and the inductance value of L2 to ensure they match the design requirements, incorporating switching frequency and desired output current.
-
*Shutdown and Mode Select (MODE/SHDN, Pin 10 and Pin 2)
- Not detailed in the description for connections, but it's essential to manage these pins correctly according to the desired operational mode (fixed frequency or burst mode)[3]. Ensure MODE/*SHDN pin is correctly configured based on the operating mode.
-
Compensation Network (VC, Pin 9)
- Connected to
- Analysis: The compensation network consisting of C10 and C12 is crucial for stabilizing the feedback loop. Ensure these capacitor values are suitable for the desired transient performance and loop stability.
