ISL8104 8V to 14V, Single-Phase Synchronous Buck Pulse-Width Modulation (PWM) Controller With Integrated Gate Drivers
The ISL8104 provides a voltage‑mode PWM controller with dual‑edge modulation, adjustable operating frequency from 50 kHz to 1.5 MHz, and an internal 0.597 V reference. It includes top‑ and bottom‑side MOSFET gate drivers capable of 1.25 A source and 2 A sink currents, and supports soft‑start, over‑current protection, and pre‑biased load start‑up.
The device is offered in 16‑lead QFN and 14‑lead narrow SOIC packages, with detailed pin‑out information, absolute maximum ratings, and recommended layout guidelines for high‑frequency operation. It is RoHS‑compliant and available in Pb‑free versions.
