Working Principles

The FPF2183 is a power switch IC that operates by controlling the flow of current between the input and output pins. When the enable pin (EN) is high, the power switch turns on, allowing current to flow from the input pin (IN) to the output pin (OUT). Conversely, when the enable pin is low, the power switch turns off, interrupting the current path.

The feedback pin (FB) monitors the output voltage and provides feedback to regulate the power switch's operation. The soft start pin (SS) controls the rise time of the output voltage during startup, preventing excessive inrush current.

Detailed Application Field Plans

The FPF2183 is widely used in various applications, including but not limited to: - Portable electronic devices - Battery-powered systems - USB-powered devices - Industrial automation - Automotive electronics
