UC3842BD1013TR – High Performance Current Mode Controller IC- SOIC-8 Package
UC3842B The UC3842B, and UC3843B 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 a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, a high gain error amplifier, a current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of input and reference under-voltage lockouts each with hysteresis, cycle−by−cycle current limiting, programmable output dead time, and a latch for single pulse metering.
Features:
- Low start-up and operating current
- Undervoltage lockout with hysteresis
- Internally trimmed reference with Undervoltage lockout
- Current limiting
- Trimmed oscillator for precise frequency control
- Current mode operation to 500khz
- Oscillator frequency guaranteed at 250khz
- Latching PWM for cycle-by-cycle
- High current totem pole output
- Automatic feed-forward compensation
