s INITIAL SETTINGS
(1) Output voltage
CH1 : Vol (V) = 1.24/R15× (R13+R14+R15) =: 2.5 (V)
CH2 : Vo2-2 (V) = 1.24/R21× (R19+R20+R21) =: 5.0 (V)
CH3 : Vo3-2 (V) = 1.24/R27× (R25+R26+R27) =: 5.0 (V)
CH4 : Vo4 (V) = 1.24/R33× (R31+R32+R33) =: 3.3 (V)
(2) Oscillation frequency
fosc (kHz) = 1200000/ (C29 (pF) × R37 (kΩ) ) =: 500 (kHz)
(3) Soft-start time
CH1 : ts (s) = 0.103×C20 (µF) =: 10.3 (ms)
CH2 : ts (s) = 0.103×C22 (µF) =: 10.3 (ms)
CH3 : ts (s) = 0.103×C24 (µF) =: 10.3 (ms)
CH4 : ts (s) = 0.103×C26 (µF) =: 10.3 (ms)
(4) Short-circuit detection time
tscp (s) = 0.70×C28 (µF) =: 7.0 (ms)
