Overview

OB6683 integrates a transition mode power factor correction (TM PFC) controller and a QuasiResonant (QR) controller in one chip. The PFC controller provides a cost effective solution for optimizing the power factor. The QR controller provides higher efficiency and lower EMI compared to conventional PWM system. OB6683 provides high level integration and high performance than conventional PFC/PWM system. The built-in TM PFC controller optimizes power conversion efficiency with reduced system cost. The intelligent PFC switching ON and OFF, zero current detection and frequency limitation mechanism enable a better efficiency under any load conditions. OB6683 features many built-in green functions to optimize power conversion efficiency at all power levels. This holds for QR operation at high power levels, as well as PFM operation at lower power levels, and ‘Extended Burst Mode’ operation at very low power or zero power (Standby) levels. At low power levels, OB6683 can turn off the PFC stage. In this way, low standby together with low system cost can be achieved. The device is also integrated many functions of protection, such as X-CAP discharge, Brownin/out protection, VCC Under Voltage Lockout (UVLO), Cycle-by-Cycle Current Limiting for PFC and QR Stage (OCP), Output Over Voltage Protection for PFC and QR Stage (OVP), Open Loop Protection for PFC and QR Stage (OLP), Programmable Over Temperature Protection (OTP), Built-in Soft Start in QR Stage, VCC Over Voltage Protection, Gate Clamp, Pin Floating Protection, and External Latch Triggering, etc. Therefore it can protect the system from damage due to occasional failure. OB6683 is offered in SOP-16 packages.
