... DCM-mode operation when PSI_L is asserted to logic low. 3 The heart of the ISL6264 is the R Technology™, Intersil's Robust Ripple Regulator modulator. The R combines the best features of fixed frequency PWM and hysteretic PWM while eliminating many of their shortcomings. The ISL6264 modulator internally synthesizes ...

... SOFT 1-DE (diode emulation) capacitor. The internal current source of 230µA is used to charge or discharge the SOFT capacitor. Intersil result, high-speed input voltage steps do not result in significant output voltage perturbations. In response to load current step increases, the ISL6264 will transiently raise the switching frequency so that response time is decreased and current is shared by two channels ...
