Transistor 2X100W stereo and mono bass amp circuits by converting 12V battery voltage (between 11v…14.4v) SG3525 DC DC voltage amplifier circuit to around 2X30…35V. There is protection against short-circuiting in both circuits and short-circuiting of the transistors at the amplifier output and giving DC voltage. The 120W subwoofer amplifier has an adjustable bass filter circuit

SG3525 Circuits SG3525 Projects SG3525 pulse width modulator PWM control integrated, can be used for the control of all kinds of switched power supply. High performance. A synchronization input to the oscillator allows multiple units to be supplied or a single unit to be synchronized to an external system clock. A wide range of dead time control can be performed with a single resistor connected between the Frequency and Discharge pins, plus a built-in soft start circuit set by an external timing capacitor.
