: Reduces electromagnetic interference (EMI) noise, aiding in regulatory compliance. Common Applications
: Certain models are rated to operate reliably at temperatures up to 105°C . Pin Configuration and Functions
: Automatically shuts down the IC if it exceeds safe operating temperatures.
: Feedback terminal for constant voltage control signals. Core Features and Protections
: Includes a power MOSFET, a current-mode PWM controller, and a frequency jittering circuit to minimize EMI.
: Monitors input voltage to prevent component failure.
: Drain/Startup terminal for the MOSFET and startup signal input. Pin 2 (S/OCP) : Source/Overcurrent Protection terminal. Pin 3 (GND) : Ground terminal. Pin 4 (VCC) : Power supply terminal for the control circuit.
: Capable of achieving high efficiency, with some benchmarks reaching up to 95% .
: Limits output current to safe levels.
The 5-pin configuration simplifies PCB layout compared to discrete designs.
