ISL6244 - Multi-Phase PWM Controller

General Description

The current carried out of this pin is proportional to output current and can be used to incorporate output voltage droop and/or load sharing.

The scale factor is set by the ratio of the ISEN resistors and the lower MOSFET rDS(ON).

Key Features

  • of this controller IC include Dynamic VIDTM technology allowing seamless on-the-fly VID changing without the need of any external components. Battery “feed-forward” is provided to allow for traditional control schemes over total input voltage variation. Output voltage “droop” or active voltage positioning is optional. When employed, it allows the reduction in size and cost of the output capacitors required to support load transients. A threshold-sensitive enable input allows the use of an extern.

® 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 the output voltage to match the programmed 5-bit DAC reference voltage.
