Overview
General description
The PUCC3801 is a current-mode Pulse Width Modulated (PWM) controller containing all the control and protection functions necessary to implement an off-line, flyback or forward converter with a minimum number of external components.
Features
• Very low start-up supply current; 50 µA typical
• Low operating supply current; 1.2 mA typical
• Accurate, internally-trimmed, fixed frequency oscillator (100 kHz). No external timing components needed
• Internal slope compensation. No external ramp components needed
• Built-in over-voltage and under-voltage detection
• High-speed over-current trip; 170 ns typical
• Over-voltage clamp on supply voltage (VDD)
• Internal divider regulates VDD to 12 V. No external divider needed
• Leading edge blanking of the current sense signal
• Control frequency modulated over a narrow band to reduce Electromagnetic Interference (EMI)
• High output drive capability; 150 ns typical rise and fall time into 2 nF load
• Wide bandwidth (10 MHz) error amplifier with external compensation pin and simple interface to optocoupler
• Accurate internal bandgap reference.Applications
• Off-line switched mode power supplies
• Laptop computer mains adaptors
• Printer power supplies.
