电流模式PWM

The UC284xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout feat • LOW START-UP AND OPERATING CURRENT \n• UNDERVOLTAGE LOCKOUT WITH HYSTERESIS \n• INTERNALLY TRIMMED REFERENCE WITH UNDERVOLTAGE LOCKOUT \n• CURRENT LIMITING \n• TRIMMED OSCILLATOR FOR PRECISE FREQUENCY CONTROL \n• CURRENT MODE OPERATION TO 500kHz \n• OSCILLATOR FREQUENCY GUARANTEED AT 250kHz \n• LA;
