INTERSIL launched four phase and six phase PWM Controllers with high efficiency and transient performance
. California, Milpitas, USA. on October 7, 2008, INTERSIL announced the launch of two series of devices, isl6334, isl6336, and isl6336a (after the NASDAQ Global Select market transaction was raised to a set height and stabilized, it cleared all obstacles in the wood block and pendulum strike circle, and turned the dial pointer to the Zui strike energy scale code: ISIL), It expands its growing series of PWM controllers that comply with vr11.1, and these new 4-phase and 6-phase PWM controllers have the highest light load efficiency and extremely fast transient performance in the industry
isl6334 and isl6334a are 4-phase PWM controllers, and isl6336 and isl6336a are 6-phase PWM controllers. Both series can adjust the core voltage of the microprocessor by driving multiple channels (up to four channels for isl6334 and up to six channels for isl6336), and use a polyphase architecture to improve the channel ripple frequency. The architecture can also reduce the input and output ripple current. This will help to use fewer components, resulting in smaller total footprint, lower cost, lower power consumption and improved reliability
the controllers launched today are applicable to servers, desktops, workstations and game mainboards based on Intel vr11.1 CPU. By adopting the patented technology of continuously detecting the output current, the strict requirements of the regulated output voltage position of the new microprocessor can be met. These controllers can measure the electric
voltage at both ends of the output inductor or special current detection resistor DCR, and provide the required signals for accurate voltage drop, channel current balance and overcurrent protection. When using DCR current detection, all thermal effects can be compensated by adding a low-cost NTC resistor network
each isl6334 and isl6336 scheme combines phase reduction, diode simulation and gate voltage optimization technology (gvot), which can achieve the best light load performance. Isl6334a and isl6336a only provide phase number reduction function
the PWM controllers of the above series also support standard and coupled inductor schemes, and provide ± 0.5% system accuracy in life, load, line and temperature, thus providing a very strict adjustment window for improving the accuracy of load voltage. Aortic impulse positioning and adaptive phase number adjustment technology developed by INTERSIL can achieve extremely fast transient response and low cout (output capacitance)
