UC3845 Current Mode PWM Controller IC DIP-8 Package

The UC3845 fixed frequency current mode controller is specifically designed for off-line and DC-to-DC converter applications offering the designer a cost effective solution with minimal external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.

Features:

• Fixed Frequency Current-Mode PWM Controller
• Trimmed Oscillator Discharge Current for Precise Duty Cycle Control
• Current Mode Operation to 500 kHz
• Automatic Feed Forward Compensation
• Latching PWM for Cycle−By−Cycle Current Limiting
• Internally Trimmed Reference with Under voltage Lockout
• High Current Totem Pole Output
• Under voltage Lockout with Hysteresis
• Low Startup and Operating Current
