In many applications, you need a low voltage to high voltage electrical equipment for use. The solar battery powered circuits, which often require a low voltage of 2.2 ~ 5.0V raised to the availability of 12V, even higher voltages. Again 3.7V to 5V boost lithium battery to supply large current portable device must be such a low voltage to the availability of 5V, 12V or 24V voltage standards, and general car is 12V car accumulator (battery loss electric and full electric voltage range 10.5V ~ 14.5V) between such a low voltage power supply 19V notebook can not make work. And requires the DC / DC converter output power in the tens of W or more. It is necessary to develop a low-voltage, high-current DC / DC boost converter. Guangdong core source - just developed a MOSFET switching device with efficient and high-performance IC controller block diagram shown in Figure 1. A typical application circuit GS3660 chip input range of 2.2 ~ 15V, the controller uses a unique control scheme, PWM (pulse width modulation) superiority, to provide an efficient, wide range of power supply voltage regulator. Having a smaller quiescent current with high efficiency at heavy loads, noise. Peripheral components using a small volume of output ripple can be satisfied, it is easy to reduce the size of the circuit and circuit costs. The circuit PWM outputs directly drive N-channel FET drive boost to achieve high current output, wide voltage supply 2.2V-15V, wide operating frequency 50KHZ-1MHZ oscillation frequency, with undervoltage protection, soft start and short circuit protection. Make the circuit more stable!
