Description
xUC3842AN AC-DC Controller and Regulator IC - DIP-8 Package is a fixed-frequency current-mode PWM controller designed for high-performance AC-DC and DC-DC power supply applications. It features an integrated precision reference, oscillator, error amplifier, current sensing comparator, and high-current totem-pole output, making it ideal for switch-mode power supplies (SMPS), offline converters, battery chargers, and industrial power systems. The UC3842AN offers low startup current, fast transient response, and cycle-by-cycle current limiting for reliable and efficient operation.
Features:
- Fixed Frequency Current-Mode PWM Controller
- Low Startup Current
- High Current Totem-Pole Output
- Integrated Precision 5V Reference
- Internal Oscillator
- Cycle-by-Cycle Current Limiting
- Under-Voltage Lockout (UVLO)
- Fast Transient Response
- High Stability Operation
- Suitable for AC-DC and DC-DC Converters
- DIP-8 Through-Hole Package
- RoHS Compliant
