RT7313GS

Overview

The RT7313GS is a Power Factor Correction (PFC) controller from Richtek USA Inc., designed for single-phase applications operating in Critical Conduction Mode (CRM). It utilizes an 8-SOP package and supports an operating junction temperature range of -40°C to 125°C. The component is currently classified as active within the manufacturer's portfolio.

Feature Summary

• Supports Critical Conduction Mode (CRM) operation for enhanced efficiency in single-phase PFC designs
• Integrated control architecture optimized for compact power supply implementations

Applications

• Single-phase AC/DC power factor correction circuits
• Consumer electronics power adapters
• LED driver power supplies

Procurement Notes

Verify current availability status directly with authorized distributors, as inventory levels fluctuate. Confirm the specific suffix 'GS' matches the required 8-SOP package variant. Ensure compliance with RoHS standards and check for any recent Product Change Notifications (PCN) or End-of-Life (EOL) announcements prior to finalizing procurement orders.

Selection Notes

Select this component for single-phase CRM PFC applications requiring high power factor correction. Consider thermal management capabilities given the 125°C junction temperature rating. Evaluate compatibility with external MOSFETs and passive components for the target power level. Compare against other Richtek CRM controllers if multi-phase interleaving is required.

Part Context

The RT7313GS belongs to Richtek's family of power management integrated circuits focused on AC/DC conversion and power factor correction. It complements other CRM controllers like the RT7315AGE, offering a solution for efficient energy conversion in standard single-phase mains-powered equipment.

Replacement Considerations

Consult official substitution guides for equivalent CRM PFC controllers. Verify pinout compatibility and electrical specifications before replacing with alternative part numbers.
