Product Introduction

The control IC UC2842A/3A/4A/5A family is a pin-compatible series of improved versions of the UC2842/3/4/5 pins. Providing the necessary functions to control the current mode switching power supply, this home has the following improved features. The starting current is guaranteed to be less than 0.5 mA. The oscillator discharge trimmed to 8.3 milliamps. In undervoltage lockout, the output stage can absorb less than 5 volts of 10mA to at least five volts of 1.2 volts

The differences between the members of this family are listed in the table below.

characteristic

Extended performance from -40°C to 125°C
Optimize offline and DC-to-DC converters
Low starting current (0.5 mA)
Side vibration discharge current
Automatic feedforward compensation
The pulse is limited by the pulse current
Enhanced load response characteristics
Undervoltage locking hysteresis
Dual pulse suppression
The totem pole outputs a large current
Internal fine-tuning bandgap datum
500 kHz operation
