Description
FAN7930 FAN7930C FAN7930B SOP-8 SMD
The FAN7930, FAN7930B, and FAN7930C series are active Power Factor Correction (PFC) controllers Packaged in a compact SOP-8 SMD surface-mount package, these chips operate in critical conduction mode (CRM) and utilize voltage-mode PWM control, meaning they do not require an input voltage-sensing network. This design minimizes internal power dissipation and optimizes efficiency, making them standard components in LCD/CRT TVs, power adapters, SMPS systems, and lighting ballasts.
Key Specifications & Features
- Operating Voltage (\(V_{CC}\)): Typically ranges from a minimum threshold of 13V up to an absolute maximum input of 20V–24V.
- Peak Gate Drive Current: +500mA sourcing and -800mA sinking capacity to directly control power MOSFETs.
- Internal Protection Matrix: Fully integrated over-voltage protection (OVP), open-feedback loop protection, and cycle-by-cycle MOSFET over-current protection (OCP).
- Performance Optimization: Features an internal Total Harmonic Distortion (THD) optimizer alongside an integrated 150μs internal startup timer.
SOP-8 Pinout Configuration
| Pin Number | Pin Name | Functional Description |
|---|---|---|
| 1 | INV | Inverting input of the error amplifier; expects a resistively divided 2.5V reference from the PFC output. |
| 2 | OVP | Dedicated input tracking secondary over-voltage anomalies if the primary INV pin system fails. |
| 3 | COMP | Output terminal of the transconductance error amplifier used for frequency compensation. |
| 4 | CS | Current sense input linked to a low-value source resistor to monitor MOSFET over-current thresholds. |
| 5 | ZCD | Zero-current detection input triggering the external power MOSFET when inductor energy reaches zero. |
| 6 | GND | System ground; data sheets note that logic and power paths should be physically isolated on the layout. |
| 7 | OUT | Totem-pole gate driver output node providing rapid turn-on and turn-off pulses to the boost switch. |
| 8 | VCC | Core operating supply voltage feed supplying both control circuitry and gate drive current. |
