UC3845B IC – (SMD SOP-8) Current Mode PWM Controller
Description:
UC3845 SMD ic
The UC3845B Current Mode PWM Controller is high performance fixed frequency current mode
controller. It is specifically designed for Off-Line and dc-to-dc converter applications offering the designer
a cost-effective solution with minimal external components. It is integrated circuits feature an oscillator,
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.
Specifications:
- 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 Undervoltage Lockout
- High Current Totem Pole Output
- Undervoltage Lockout with Hysteresis
- Low Startup and Operating Current
