Technical Documentation Cigarette Lighter Charger LCH–2 Oscillator The converter operates at a fixed frequency of 300 kHz, produced by oscillator N110A. A suitable operating voltage for the comparator positive input is set by resistor divider R112/R114. Positive feedback from the comparator output is supplied by R111 in parallel with C104. When the comparator output is high C110 is charged through R110 and R113 until the voltage at the negative input exceeds the positive input.
