Voltage Regulator Current Limit Module 3.3V Out

This project is focused on designing a compact and efficient voltage regulator module that delivers a stable 3.3V output while integrating a programmable current limit feature. Targeted at applications that demand reliable power regulation and robust protection against overcurrent or short circuit conditions, this design leverages the ultra-low switch SY6280 along with supporting passive components for decoupling, filtering, and current sensing. The module is intended for integration into systems where safe and efficient power management is critical, ensuring both performance and long-term stability.

The component U1 in your project is an integrated circuit with the part number SY6280AAAC manufactured by Silergy Corp. It serves as a voltage regulator with current limiting capabilities. Here's a brief overview of its function:

Voltage Regulation: The SY6280 is designed to provide a stable output voltage, in this case, 3.3V at the output pin (VOUT). It receives an input voltage at the VIN pin and regulates it to the desired output level.
Current Limiting: The IC includes an internal mechanism to limit the current flowing through it to prevent damage from overcurrent conditions. This is controlled via the ISET pin, which is connected to R1 to set the desired current limit.
Enable Functionality: The EN pin is used to enable or disable the device. When connected to a high voltage level, the regulator is active, while connecting it to a low voltage level can disable it.
Protection Features: Besides current limiting, this device also provides short-circuit protection, ensuring the circuit is safe under fault conditions.

The SY6280 is highly efficient and well-suited for applications like IoT and embedded systems where power management and circuit protection are crucial.

what is the maximum voltage input?

3mo

copilot

The SY6280 integrated circuit is a voltage regulator that can typically handle a maximum input voltage of 5.5V. This is a common maximum input rating for many similar low-dropout (LDO) regulators, but it is always best to check the specific datasheet for the exact maximum input voltage, as there can be variations based on different part variants or conditions. If your input voltage exceeds this rating, it could damage the IC.
