Description
The highly integrated SG6742ML/MR PWM controller provides several features to enhance the performance of flyback converters.
To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency at light-load conditions. To avoid acoustic-noise problems, the minimum PWM frequency is set above 22KHz. The green-mode function enables the power supply to meet international power conservation requirements. With the internal high-voltage startup circuitry, the power loss due to bleeding resistors is also eliminated. To further reduce power consumption, SG6742ML/MR is manufactured using the BiCMOS process, which allows an operating current of only 2.7mA.
Features
? High-Voltage Startup
? Low Operating Current: 2.7mA
? Linearly Decreasing PWM Frequency to 22KHz
? Frequency Hopping to Reduce EMI Emission
? Fixed PWM Frequency: 65KHz
? Peak-Current-Mode Control
? Cycle-by-Cycle Current Limiting
? Leading-Edge Blanking
? Synchronized Slope Compensation
? Internal Open-Loop Protection
? GATE Output Maximum Voltage Clamp: 18V
? VDDUnder-Voltage Lockout (UVLO)
? VDDOver-Voltage Protection (OVP)
? Programmable Over-Temperature Protection (OTP)
? Internal Latch Circuit (OVP, OTP)
? Internal Sense Short-Circuit Protection
? Build-in 5ms Soft-Start Function
? Constant Power Limit (Full AC Input Range)
? Internal OTP Sensor with Hysteresis
Applications
General-purpose switch-mode power supplies and flyback power converters, including:
? Power Adapters
? Open-Frame SMPS
