ML4800IP

Overview

The onsemi ML4800IP is an integrated circuit designed for Power Factor Correction (PFC) applications, functioning as a combined PFC and PWM controller. It utilizes average current mode control to optimize power efficiency. The device operates with a switching frequency of 76 kHz and supports a minimum frequency of 81 kHz. It features an operating supply current of 5.5 mA and includes under-voltage lockout (UVLO) at 2.8 V. The component is rated for a wide temperature range from -65°C to +150°C and is available in a 16-pin PDIP package.

Feature Summary

• Combines PFC and PWM control functions in a single integrated circuit
• Utilizes average current mode control for efficient power factor correction
• Designed for operation across extended industrial temperature ranges

Applications

• Power factor correction stages in power supplies
• AC-DC conversion systems requiring high efficiency
• Industrial power management equipment

Procurement Notes

Verify the specific suffix and package type against official datasheets before procurement. Confirm availability status as manufacturing status may vary. Ensure compatibility with existing thermal management solutions given the wide operating temperature range. Cross-reference pinouts with legacy designs if replacing older components.

Selection Notes

Select this component for applications requiring integrated PFC and PWM control without external discrete controllers. Consider the 76 kHz switching frequency for EMI filtering requirements. Evaluate the 16-PDIP package for through-hole mounting needs. Verify that the average current mode control meets the specific dynamic response requirements of the target power supply design.
