The ISL54103 DDC Accelerator (DDCA) is a dual active pull-up bus termination that increases data transfer speed on the DDC 2-wire serial bus interface. DDCA uses two internal voltage references per channel and two comparators. After the voltage on the data line exceeds the first threshold (VTRIPL), the boost pull-up current source speed transition is initiated. When the ...

The ISL6753 is a high-performance, low-pin-count alternative, zero-voltage switching (ZVS) full-bridge PWM controller. Like the ISL6551, it adjusts the resonant switching delay by driving the high-side FET at a fixed 50% duty cycle while the trailing edge of the low-side FET modulates the switching delay. In contrast, this algorithm provides the equivalent efficiency and impro...
