... PWM while eliminating many of their shortcomings. The ISL6265 modulator internally synthesizes an analog of the inductor ripple current and uses hysteretic comparators on those signals to establish PWM pulse widths. Operating on these large-amplitude, noise-free synthesized signals allows the ISL6265 to achieve lower 3 Technology™, Intersil's 3 modulator FN6599.1 May 13, 2009 ...

... Modulator The ISL6265 modulator features Intersil’s R hybrid of fixed frequency PWM control and variable frequency hysteretic control (see Figure 5). Intersil’s R technology can simultaneously affect the PWM switching frequency and PWM duty cycle in response to input voltage 3 and output load transients ...
