Product overview

Overview

High Performance Current Mode Controllers
The UC3844B, UC3845B series are high performance fixed frequency current mode controllers.
They are specifically designed for Off−Line and dc−dc converter applications offering the designer a cost−effective solution with minimal external components.
These integrated circuits feature an oscillator, a temperaturecompensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.
Features
• Trimmed Oscillator for Precise Frequency Control
• Oscillator Frequency Guaranteed at 250 kHz
• Current Mode Operation to 500 kHz Output Switching Frequency
• Output Deadtime Adjustable from 50% to 70%
• 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

These Devices are Pb−Free and are RoHS Compliant
• NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
