Overview
The ML4805CP is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for average current mode control applications. It operates within a switching frequency of 212 kHz and supports through-hole installation in a PDIP-18 package. The component functions reliably across an operating temperature range from 0°C to +70°C. Classified under PMIC - Power Management ICs, this device integrates PFC control capabilities suitable for AC/DC converter topologies requiring efficient power factor correction.
Feature Summary
- Supports average current mode control for improved power factor correction performance
- Integrated into the ML4800 series family for standardized PFC design implementations
- Designed for through-hole mounting to facilitate specific PCB layout requirements
Applications
- AC/DC converter designs requiring power factor correction
- Power management integrated circuits for consumer electronics
- Industrial power supply systems utilizing average current mode control
Procurement Notes
Verify component authenticity and datasheet alignment before integration. Confirm that the PDIP-18 package and 212 kHz switching frequency meet system specifications. Check for obsolescence status as availability may be limited. Ensure thermal management aligns with the 0°C to +70°C operating range. Validate RoHS compliance details if required by target market regulations.
Selection Notes
Select this component when average current mode PFC control is required in a through-hole DIP-18 package. Consider the 212 kHz switching frequency for magnetic component sizing. Evaluate the 0°C to +70°C industrial temperature range against environmental conditions. Compare against other ML4800 series variants if different pinouts or frequencies are needed.
Part Context
Part of the ML4800 series from onsemi, focusing on power factor correction solutions. Belongs to the broader PMIC category, specifically supporting AC/DC conversion efficiency. Designed for applications needing robust PFC control without complex digital interfaces.
Replacement Considerations
Check for direct pin-compatible alternatives within the ML4800 series. Verify if FAN4800CNY offers similar functionality with updated features. Consult onsemi documentation for recommended upgrades or end-of-life notifications.
