UC2843AQD8RQ1 General Description
The UC2843A-Q1 control device is a pin-for-pin compatible improved version of the UC2843. Providing the necessary features to control current mode switched mode power supplies, this device has the following improved features. Start up current is specified to be less than 0.5 mA. Oscillator discharge is trimmed to 8.3 mA. During undervoltage lockout, the output stage can sink at least 10 mA at less than 1.2 V for VCC over 5 V.
Features
- Qualified for automotive applications
- Extended temperature performance of –40°C to 125°C
- Optimized for off-line and DC-to-DC converters
- Low start-up current (<0.5 mA)
- Trimmed oscillator-discharge current
- Automatic feed-forward compensation
- Pulse-by-pulse current limiting
- Enhanced load-response characteristics
- Under-voltage lockout with hysteresis
- Double-pulse suppression
- High-current totem-pole output
- Internally trimmed bandgap reference
- 500-kHz operation
-
Low RO Error Amp
