SG PWM control chip highly integrated features such as built-in slope compensation

Products to promote good corporate SG recently produced highly integrated PWM control chip - SG6842 series. The chip used in the general AD / DC switching power supply, power system designers meet the requirements, and LM324AN datasheet and to reduce product design costs.

SG6842 SG series of non-use of on-time modulation (Off Time Modulation) patents, in the light load and LM324AN price and no load, the PWM frequency will decrease as the load to reduce its frequency, and LM324AN suppliers and with the patented Burst Mode Control , the standby power consumption to a minimum. SG6842 Series built-in slope compensation, can work in continuous mode, and an increase in a wide voltage operation (90V ~ 264VAC) power when the conversion efficiency. In addition, it built-in short circuit protection, over temperature / over-voltage latch (Latch-Off) circuit, Leading Edge Blanking circuit, over temperature protection from the set point (OTP) and other functions, peripheral devices can be minimized, thereby reduce design complexity SMPS, SMPS products help engineers shorten development time.

SG6842 series of products using BiCMOS technology, ultra-low startup current (8uA), operating current (3.7mA), can reduce power consumption. Currently available in DIP and SOP 8 PIN packaging, the main application covers the LCD monitor market, LCD-TV, DVD, N / B adapter. SG6842 Another Jitter version (SG6842J), with a frequency hopping function to facilitate the issue of engineers in the EMI deal with applications.

SG6842J product was available for sampling in the second quarter.
