Description

The UC3842B , UC3843B series are high performance fixed frequency current .. current and the equivalent input divider source resistance. The Error Amp UC3842 is an integrated pulse width modulator the UC3842 is optimized for efficient power sequen- nuous, controlling peak current is nearly equivalent . 3. UC3842A=Frequency: RT=10K ,CT=3.3nF 47KHz-57KHz. 4. UC3842B = Frequency: RT=10K ,CT=3.3nF 49KHz-55KHz. 5. Totem Pole design for MOSFET. current and the equivalent input divider source resistance. The Error Amp Output (Pin 1) is provide for external loop compensation (Figure 31). The output Jul 24, 2015 Resonance equivalent parasitic capacitance.
