Overview

® ISL6244 Data Sheet November 2003 FN9106.
1 Multi-Phase PWM Controller The ISL6244 provides core-voltage regulation by driving 2 to 4 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 ISL6244 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.
A high-bandwidth error amplifier drives t...
