供应电源管理IC电压模式PWM 控制器6754MR
Fairchild 公司的FAN6754 是高度集成的绿色模式(Green-Mode) PWM控制器,以增强反激电源转换器的性能.为了最小化待机功耗, 绿色模式功能提供关时调制,连续降低轻负载的开关频率.工作电流1.7mA,固定PWM频率为65KHz,可线性地降低到22KHz,主要用于通用开关电源(SMPS)和包括电源适配器在内的反激式电源转换器.本文介绍FAN6754主要特性,方框图以及应用电路.FAN6754: Highly Integrated Green-Mode PWM ControllerThe highly integrated FAN6754 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 continuously decrease the switching frequency under light-load conditions.Under zero-load and very light-load conditions, FAN6754 saves PWM pulses by entering deep burst mode. This burst mode function enables the power supply to meet international power conservation requirements.FAN6754 integrates a frequency-hopping function internally to reduce EM...
