The control IC UC2842A/3A/4A/5A family is a pin-compatible family of improved versions of the UC2842/3/4/5-pin. Providing the necessary functions to control current mode switching power supplies, this family has the following improved features. The start-up current is guaranteed to be less than 0.5 mA. The oscillator discharge is trimmed to 8.3 mA. In undervoltage lockout, the output stage can absorb less than 10mA to 1.2 voltstargetV CC at least five
The differences between the members of this family are listed in the table below.
characteristic
- Performance with extended temperature from -40°C to 125°C
- Optimize offline and DC-DC converters
- Low start-up current ("0.5 mA")
- Side vibration discharge current
- Automatic feed-forward compensation
- The pulse is limited by the pulse current
- Enhanced load response characteristics
- Undervoltage lockout
- Double pulse suppression
- The totem pole outputs a large current
- Internal fine-tuning bandgap reference
- 500 kHz operation
