Intersil ISL6535 Synchronous Buck PWM Controller Datasheet
The ISL6535 synchronous buck PWM controller is designed for demanding DC/DC converter applications. It provides over‑current fault protection, a precise 0.597 V internal reference, and voltage‑mode control with fast transient response. The device supports a wide input range and can be configured for both SOIC and QFN packages.
Key features include a programmable triangle‑wave oscillator (200 kHz‑1.5 MHz), high‑speed MOSFET gate drivers (up to 1.25 A source/2 A sink at 12 V), and a built‑in soft‑start circuit. The datasheet also covers layout guidelines, absolute maximum ratings, and detailed pin descriptions for system integration.
