The NCP1200P60G is a fixed-frequency current-mode PWM controller designed for off-line power supply applications. It typically comes in an 8-pin DIP (Dual In-line Package) configuration. Here’s a brief overview of its pin functions:
1. Pin 1 (GND): Ground connection for the controller.
2. Pin 2 (FB): Feedback input used for voltage regulation. It monitors the output voltage and adjusts the PWM duty cycle accordingly.
3. Pin 3 (CS): Current sense input. It monitors the current through the power switch and provides cycle-by-cycle current limiting.
4. Pin 4 (OSC): Oscillator pin. It sets the switching frequency and can be used for frequency synchronization.
5. Pin 5 (VCC): Supply voltage input for powering the controller.
6. Pin 6 (DRIVE): Output drive for the power MOSFET gate.
7. Pin 7 (NC): No connection, typically reserved for future use or maintaining pin compatibility with other models.
8. Pin 8 (HV): High-voltage startup pin. It connects to the input voltage and incorporates a startup current source to power the IC from the high-voltage DC input.
The NCP1200P60G is commonly used in applications such as adapters, flat-panel displays, and other compact power supplies.
