ISL6569A Multi-Phase PWM Controller NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc DATASHEET FN9092 Rev 2.00 Dec 29, 2004 The ISL6569A provides core-voltage regulation by driving two interleaved synchronous-rectified buck-converter channels in parallel. Interleaving the channel timing results in increased ripple frequency which reduces input and output ripple currents. The reduction in ripple results in lower component cost, reduced dissipation, and a smaller implementation area. The ISL6569A uses cost and space-saving rDS(ON) sensing for channel current balance, active voltage positioning, and over-current protection. Output voltage is monitored by an internal differential remote sense amplifier.
