The ISL78215 family of adjustable frequency, low power, pulsewidth modulating (PWM) current mode controllers is designed fora wide range of power conversion applications including boost,flyback, and isolated output configurations. Peak current modecontrol effectively handles power transients and providesinherent overcurrent protection.
This advanced BiCMOS design is pin compatible with the industrystandard 384x family of controllers and offers significantlyimproved 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 falltimes.
The ISL78215 is tested to AEC-Q100 specifications.
