ISL6269 - High-Performance Notebook PWM Controller

Features

  • of fixedfrequency PWM and hysteretic PWM while eliminating many of their shortcomings. R3 technology employs an innovative modulator that synthesizes an AC ripple voltage signal VR, analogous to the output inductor ripple current. The AC signal VR enters a window comparator where the lower threshold is the error amplifier output VCOM.

Integrated MOSFET drivers, 5V LDO and bootstrap diode result in fewer components and smaller implementation area. Intersil’s R3 technology combines the best features of fixedfrequency PWM and hysteretic PWM while eliminating many of their shortcomings.
