FAN4803CP2

Overview

The FAN4803CP2 is a Power Factor Correction (PFC) and PWM controller combination integrated circuit manufactured by onsemi. It operates in average current mode with a fixed switching frequency of 67 kHz. The device is housed in an 8-pin PDIP package designed for through-hole mounting. It supports a supply voltage range of 10V to 15V and functions within an operating temperature range of 0°C to +70°C. The component integrates PFC control with post-regulation capabilities.

Feature Summary

• Combines power factor correction and pulse width modulation control in a single unit
• Utilizes average current mode control architecture
• Includes post-regulator functionality for output voltage stabilization

Applications

• Power supplies requiring combined PFC and regulation
• AC-DC conversion systems
• General purpose power management circuits

Procurement Notes
