Advantage: Low cost
Disadvantage:
(1) Undesirable reliability, single performance, no overtemperature and short circuit-proof measures.
(2) Inputs direct current voltage, but controls input constant charge current by limiting maximum switched current peak, its precision is not accurate enough.
(3) As 34063 belongs to a 1.5-A switched current PWM+PFM mode (no interior error magnifier), its automobile charge inputs relatively larger wave of direct voltage and current, the wave is not pure enough and its ability to input current is limited. (often been seen in low-end automobile charge ranging from 300 ma to 600 ma)
