Power connector suitable for beginners

This power connector adopts the 10-pin single-in-line plastic package integrated circuit I-A4420 with radiator produced by B Benfuyang Company . Its output power is 5.5W, which is especially suitable for car radios, radios, and other applications. Portable and desktop radio recorders
are used as audio power amplifiers. The characteristics of this circuit are high gain (up to 50dB), large output power (5.5W), low noise,
small distortion, and low load (2fl) operation. It also has short circuit and overload protection circuit ports internally. When the load is short- circuited, Signal cut off. And
can automatically resume normal work. Since this circuit has a balance and tone circuit, and the two channels are independent, the high and low frequencies can be
adjusted arbitrarily. When coupled with the speakers introduced below, the music released will have a strong stereo effect and rich layers. It is a relatively
ideal power connector. Its working voltage is 1ZV, and the circuit principle is shown in Figure 5-93. Single integrated circuit I)A4420 spare pin
