FAN4803 PFC and PWM Power Supply Controller IC SOIC-8 SMD

The FAN4803 is an 8-pin surface-mount controller IC for AC-DC switch-mode power supplies. It combines a power factor correction (PFC) controller for the input stage with a pulse-width modulation (PWM) controller for the DC-DC converter stage. Separate PFC and PWM outputs allow the IC to control both stages from one package.

Key Features:

• Combines PFC and PWM control in a single IC
• 8-pin SOIC surface-mount package
• Separate PFC and PWM driver outputs
• Dedicated current-sense inputs for PFC and PWM current limiting
• 67 kHz nominal PFC switching frequency
• 67 kHz or 134 kHz nominal PWM switching frequency, depending on the variant
• Operating temperature range of 0°C to 70°C
• Designed for AC-DC switch-mode power supplies with active PFC
