ISL6745 is a low-cost, dual-ended controller that is primarily used in full-bridge and half-bridge topologies for power and line-regulated bus converters. The device features precise switching frequency control, adjustable soft start, and overcurrent shutdown protection. Additionally, the ISL6745 can precisely adjust the MOSFET non-overlap dead time down to 35 ns, allowing power designers to optimize the efficiency of open-loop bus converters. The ISL6745 also includes a voltage control input suitable for closed-loop PWM control and line-voltage feed-forward control.
The ISL6745 is a low‑cost dual‑channel bridge controller designed for full‑bridge and half‑bridge topologies in AC‑DC and DC‑DC converters. It offers precise switching‑frequency control up to 1 MHz, adjustable soft‑start, and over‑current protection, with a minimum dead‑time of 35 ns.
The device is supplied in a 10‑lead MSOP package, is RoHS‑compliant and Pb‑free, and includes features such as 1 A MOSFET gate drive, input undervoltage lockout, thermal shutdown at 145 °C, and a wide operating temperature range from –40 °C to 105 °C. This manual is written in Chinese.
