... DCM-mode operation. 3 The heart of the ISL6266A is 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 ISL6266A modulator internally ...

... Deeper Sleep to Active mode, holding DPRSLPVR LOW results in maximum dV/dt. Therefore, the ISL6266A is IMVP-6+ compliant for DPRSTP# and DPRSLPVR logic. Intersil result, high-speed input voltage steps do not result in significant output voltage perturbations. In response to load current step increases, the ISL6266A will transiently raise the switching frequency so that response time is decreased and current is shared by two channels ...

Overcurrent protection is tied to the voltage droop, which is determined by the resistors selected as described in “Component Selection and Application” on page 22. After the load-line is set, the OCSET resistor can be selected to detect overcurrent at ...
