PUCC3801T規(guī)格書詳情
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.
