Description
The UCC3802DTRG4 is an AC DC converter and offline switcher electronic component model. It is a current-mode Pulse Width Modulated (PWM) controller that contains all the control and protection functions needed to implement an off-line, flyback or forward converter with a minimum number of external components.
Specifications and features
The UCC3802DTRG4 has the following 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
Application Scenarios
The UCC3802DTRG4 is ideal for use in the following applications:
- Off-line switched mode power supplies
- Laptop computer mains adaptors
