Improved Industry Standard Single-Ended Current Mode PWM Controller

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.

Peak current mode control effectively handles power

transients and provides inherent overcurrent protection.

This advanced BiCMOS design is pin compatible with the

industry standard 384x family of controllers and offers

significantly improved performance. 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.
