Need easy science and technology gives new product again, KP126X, HPF is not had stick a capacitance, the BOM that gives you decreases ~ reducing weight

   Capacitance double rose in price! As the bitter fleabane of car electron and smartphone industry suddenly develops, the price that sticks a capacitance is gone forever along with wind, leave my generation apprentice to hurt Bei only. One when did not call formerly somewhat sticks a capacitance, become BOM to express Chongzhongzhi’s heavy presence nowadays, real experience you are indifferent to me yesterday, I let the counterattack that your make friends with a man of higher position does not remove today, become engineers of LED power source in the heart faint painful.
      How should do so? It is to search of course surely easy! We need easy urgent everybody the place of engineers is urgent, look please, should become should become ~

Surely easy

      Leave not happy, stimulate not excited! Feel the life was full of a hope again! IC of drive of segregation of tall PF blame goes VDD goes Comp capacitance plan so by need easy belt arrives beside you understandingly, surely easy KP126X, solve young associate people an extremely urgency.

     This product (KP126X) advocate hit tall P to be not segregation market, like old product KP106X(C) , have inside buy 500V and 650V and outside seal controller version, can satisfy your place have rendered great service to lead the design requirement of class; Outside buy OVP a resistor, can realize high accuracy OVP to protect a function; High-pressured power supply and inside buy annulus road adjusts, leave out starts resistor, VDD and Comp capacitance, implementation acme is concise design.

Main distinguishing feature:

Without VDD capacitance, without Comp capacitance, without the resistor that start
Inductance of on-the-spot odd winding, need not assist winding
 Exceed the fast <300mS that start, high power element > 0.9, precision of ±3% constant current
As good as at taking the surge property of VDD capacitance plan
Follow syntonic job pattern, improve systematic efficiency
Output OVP is successive and adjustable
 

Controller and inside buy MOS can offer an alternative

   So what does KP126X photograph keep apart plan to have than traditional tall P different?
     1, without VDD capacitance. Because Buck has the presence of dead band, input voltage lowest not under output voltage, reason KP126X gives IC power supply by the voltage after the bridge directly;
     2, without Comp capacitance. Road of annulus of the buy inside KP126X adjusts, implementation does not have the slow annulus tall P of VDD capacitance to adjust;
     3, OVP resistor. KP126X is on-the-spot framework, OVP cannot use traditional float ground cent to press control. But surely easy have inside buy OVP controls a technology, even if inside buy OVP also can accomplish accurate control, and need an OVP resistor only;
     4, in all framework. In all framework relatively float ground can realize more advantageous EMC character.
