The ISL6840, ISL6841, ISL6842, ISL6843, ISL6844, ISL6845 family of adjustable frequency, low power, pulse width modulating (PWM) current mode controllers is designed for a wide range of power conversion applications including boost, flyback, and isolated output configurations. Features include low operating current, 60µA start-up current, adjustable operating frequency to 2MHz, and high peak current drive capability with 20ns rise and fall times.
The ISL6840‑ISL6845 family are adjustable‑frequency, low‑power PWM current‑mode controllers designed for boost, flyback, and isolated power conversion applications. They offer peak current mode control, over‑current protection, and a BiCMOS design that is pin‑compatible with the industry‑standard 384x family.
Key features include a 60 µA start‑up current, adjustable switching frequency up to 2 MHz, 20 ns rise/fall times, and high‑current gate drive capability. The devices are offered in 8‑lead SOIC, MSOP, and DFN packages and are RoHS‑compliant Pb‑free versions.
