VPS6501
VPS6501 is a push-pull transformer driver designed specifically for small volume, low standby power consumption, and low-power isolation power supplies. Its periphery only needs to be matched with simple input and output filtering capacitors, isolation transformers, and rectification circuits to achieve isolation power supplies with 3.3V or 5V input, 3.3V~24V output, and output power of 1-2W.
The VPS6501 chip integrates an oscillator internally, providing a pair of high-precision complementary signals to drive two N-channel MOSFETs. The internal design of the chip follows a symmetrical structure, which can effectively ensure the high symmetry of the two power MOSFETs and avoid circuit bias during operation. The chip is designed with a high-precision dead zone control circuit to ensure that there is no common phenomenon under various working conditions.
