Constant current (DC) power supply.

Wi-Fi LED strip controller made with few goals: Dual voltage support 12V and 24V 2 independent channels for color temperature adjustments No high pitch noise in all modes Powerful enough to handle current up to 17.5A (in total, limited by connectors) Control buttons on the device body Connectors for external buttons Can be used with already installed LED strips Support of open source firmware, like https://esphome.io/

A common return path for electric current. Commonly known as ground.

The TPS25200 is a 5-V eFuse with precision current limit and overvoltage clamp. The device provides robust protection for load and source during overvoltage and overcurrent events.

Here is a simple USB powered lamp that can be used to light your desktop during power failures. The circuit operates from the 5 Volt available from the USB port. The 5V from the USB port is passed through current limiting resistor R2 and transistor Q1. The base of transistor Q1 is grounded via R1 which provides a constant bias voltage for Q1 together with D2. The diode D1 prevents the reverse flow of current from battery. C1 is used as a noise filter. Two white LED’s are used here for the lamp, you can also use a 2 V torch bulb instead of LED’s. LED D3 indicates connection with USB port.

The J175, J176, MMBFJ175, MMBFJ176, and MMBFJ177 are a series of P-Channel switches designed and manufactured by onsemi™, suitable for low-level analog switching, sample-and-hold circuits, and chopper-stabilized amplifiers. These components are sourced from process 88, indicating a specific manufacturing technique employed by onsemi™ to ensure consistent performance and reliability. The devices are offered in both TO-92 and SOT-23 packages, catering to a variety of mounting preferences and application requirements. They are characterized by their ability to handle a drain-gate voltage of -30V, a gate-source voltage of 30V, and a forward gate current of 50 mA. Operating and storage junction temperature ranges are specified from -55 to +150°C, ensuring robustness across a wide range of environmental conditions. With features like low on-resistance and high transconductance, these components are optimized for efficient signal modulation and minimal power loss, making them highly suitable for precision applications in analog signal processing.
