is a favorite electronic product of many people because they think it is the crystallization of the designer and the embodiment of technology, but everyone knows that the update iteration of electronic products is too fast. This year's flagship will fall to the bottom next year, especially When you buy too many electronic products, you will not let all the electronic products be covered with rain and dew, and the freshness will fall into the cold. I am an Aquarius. Others say that Aquarius loves the new and dislikes the old. Others say it is innovation. I believe in this. But our UnionPay has a good chip that we have to say, and it has not been liked by customers and disliked the old. It has long been loved by customers-the U6117 switching power supply chip.
UnionPay U6117 switching power supply chip is a high-performance current mode PWM offline flyback converter power switching application. In U6117, a high-precision 65kHz switching frequency oscillator is internally equipped with a frequency jitter function to optimize EMI performance. The chip uses green energy-saving mode and hiccup mode to work, and can guarantee a standby power consumption of less than 75mW for applications less than 40W.
UnionPay U6117 switching power supply chip integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle-by-cycle current limit, short circuit protection (SCP), overload protection (OLP), Overheat protection, soft start, VDD clamp and CS pin open circuit protection, etc.
Main features of UnionPay U6117 switching power supply chip:
supports DCM and CCM control
±1% CV adjustment, fast dynamic response
standby power consumption
current mode control
fixed 65KHz switching frequency
green power-saving mode operation, optimized loop control
ultra-low startup and operating current
integrated current mode control with internal slope compensation
integrated line voltage and inductance compensation Constant current technology
integrated self-recovery mode protection function:
VDD under-voltage protection (UVLO)
VDD over-voltage protection (OVP)
over-temperature protection (OTP)
cycle-by-cycle current limit
overload protection (OLP)
short circuit protection (SCP)
leading edge blanking (LEB)
CS pin open circuit protection
I have to say that the switching power supply chip U6117 is indeed very good.No matter where it is used, it has stable performance, high integrated circuits and simplified peripherals. The most important thing is low cost and favorable price.
