VPS8703B
VPS8703B is a transformer driver designed specifically for small volume, low standby power consumption micro 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 an input voltage of 6-30V, multiple output voltages, and an output power of 1-10W. VPS8703B integrates two N-channel power MOSFETs and two P-channel power MOSFETs internally, forming a bridge connection method. The integrated oscillator inside the chip provides a pair of high-precision complementary signals, which can effectively ensure the high symmetry of the two power MOSFET drives and avoid circuit bias during operation. VPS8703B integrates frequency synchronization function and multiple protection methods internally. In CLK, an external clock signal is input, and VPS8703B outputs two complementary drives with a half frequency of the external clock. At the same time, a highly symmetrical dead zone control circuit is designed internally to ensure that there is no common phenomenon under various working conditions; Integrated overcurrent detection protection and over temperature protection to prevent device damage in abnormal situations such as short circuits in the output of the switching power supply.
