UC3842G
High peak current associated with capacity loads necessitate careful grounding techniques. Timing and bypass
capacitors should be connected close to pin5 in single point GND.
During Under-Voltage Lockout, the output driver is biased to a high impedance state. Pin6 should be shunt to
GND with a bleeder resistor to prevent activing the power switch with output leakage currents.
Error amplifier can source or sink up to 0.5mA
