uPC1342V internal circuit principle

The internal circuit principle of FePC1342V is shown in Figure 2-124. It consists of preamplifier, power driver, and complete constant current
, constant voltage, soft start, protection, temperature compensation and other circuits. The preamplifier of the circuit adopts
the complementary symmetrical differential circuit used in II: amplifiers, supplemented by a mirror constant current source and a constant current source load, which effectively ensures the high technical
indicators of the circuit. The midpoint voltage deviation of the circuit is less than ±50mVo. The drive output design has sufficient driving power. The driving power
can be from 50w to 110, IV. The normal operating voltage range is ±20V ~ ±52V. The ultimate operating voltage is ±70V. Recommended
work The voltage is ±46V. The main electrical parameters are shown in Table 2-330. The external circuit debugging of this device is very simple. You only need to adjust
the quiescent current. This is incomparable with the use of discrete components to make power amplifier circuits.
