The UC3823A with UC3823B and UC3825A with UC3825B PWM controller series are improved standard UC3823 with UC3825 family versions. The number of circuit blocks that have been made with the performance enhancement. The error amplifier has a gain-bandwidth product of 12 MHz and an input offset voltage of 2 millivolts. The current limit threshold is guaranteed to a tolerance of 5%. The discharge current of the oscillator is specified as 10 mA for accurate dead time control. Frequency accuracy increased to 6%. The start-up supply current, typically 100μA, is ideal for off-line applications. Output drivers are redesigned to actively sink during UVLO without current starting current specification charges. In addition, the peak current capability of 2 per output is in transition.
characteristic
- Improved PWM for UC3823/UC3825 versions
- Suitable for voltage-mode or current-mode control methods
- In practice, the switching frequency is 1 MHz
- 50 - ns propagation delay to output
- High-current dual totem (peak of 2) pole output
- Side vibration discharge current
- Low 100μA start-up current
- The pulse passes through a pulsed current limiting comparator
- The latch is restarted with a full-cycle overcurrent comparator
