5 / 12 page UC3842/UC3843/UC3844/UC3845 5 Figure 2. Under Voltage Lockout During Under-Voltage Lock-Out, the output driver is biased to a high impedance state. Pin 6 should be shunted to ground with a bleeder resistor to prevent activating the power switch with output leakage current. Figure 3. Error Amp Configuration Figure 4. Current Sense Circuit Peak current (IS) is determined by the formula: A small RC filter may be required to suppress switch transients. UC3842/44 UC3843/45 I S MAX () 1.0V R S ------------ = |
