UC3843AN Description
The UC3843AN family of control ICs is an enhanced version of the UC3843AN family that is pin-for-pin compatible. This class of devices has numerous improved characteristics, including the ability to regulate current mode or switched-mode power supply. The output stage can sink at least 10 mA at less than 1.2 V for VCC above 5 V during UVLO, while the oscillator discharge is cut to 8.3 mA during startup.
UC3843AN Features
? Compensation for Feedforward is done automatically.
? Current Limiting on a Pulse-by-Pulse Basis
? Load Response Characteristics that are Improved
? Hysteresis Undervoltage Lockout
? Pulse Suppression on Both Sides
? Totem Pole Output with a High Current
? Bandgap Reference with Internal Trimming
? Operation up to 500 kHz
UC3843AN Applications
? Power Supplies with Switching Modes (SMPS)
? DC-DC Converters (DC-DC Converters)
? Energy Modules
? Power supply for industry
? PSU that runs on batteries
