Description
ON SEMICONDUCTOR UC3843BD1G Current Mode Controller, 25V-12V supply, 500 kHz, 13.4V/200mA out, SOIC-8The UC3843BD1G is a high performance fixed frequency Current Mode Controller specifically designed for OFF line and DC DC converter applications. This integrated circuit features a trimmed oscillator for precise duty cycle control, a temperature compensated reference and high gain error amplifier, current sensing comparator and a high current totem pole output ideally suited for driving a power MOSFET. Also includes protective features consisting of
- Trimmed oscillator for precise frequency control
- 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 start-up and operating current
