概要

The ISL78215 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.

The ISL78215 is tested to AEC-Q100 specifications.
