Check for PWM pulses to drive the MOSFET.
| Pin | Name / Function | Verified Measured Voltage (Example) | Description / Verified Notes | | :--- | :--- | :--- | :--- | | | Power Input (VIN) | 12V | Primary power supply for the IC's internal driver stage. | | 2 | Enable / On/Off Control | 0V (Off) / >2V (On) | A logic-high signal here typically enables the backlight driver. | | 3 | Feedback / Current Sense | Varies | Connected to a current-sensing resistor to monitor LED current for regulation. | | 4 | Over-Current Protection (OCP) | Varies | Monitors the current. If too high, the IC shuts down to protect the circuit. | | 5 | Dimming Control (PWM) | 2.5V (Typical) | Receives a PWM signal to control the brightness of the backlight. | | 6 | Ground (GND) | 0V | Common ground reference for the IC. | | 7 | Oscillator / Timing | Varies | An external resistor or capacitor sets the internal switching frequency. | | 8 | Gate Drive Output | Varies | Drives the external MOSFET that switches the main current through the LED inductor. | | 9 | Over-Voltage Protection (OVP) | ~1.55V (Normal) / 0.8V (Fault) | Monitors the boosted output voltage. Critical for verifying proper operation . | | 10 | Reference / Compensation | 3.1V (Typical) | Often provides an internal voltage reference or compensation network connection. |
