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.
- 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
Package Includes :
1 x UC3845 Current Mode PWM Controller IC DIP-8 Package
