Rev 1.00
December 7, 2013 Improved Industry Standard Single-Ended Current Mode PWM Controller
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, 60ВµA 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. Features 1A MOSFET Gate Driver 60ВµA Start-up Current, 100ВµA Maximum 25ns Propagation Delay Current Sense to Output Fast Transient Response with Peak Current Mode Control Adjustable Switching Frequency to 2MHz 20ns Rise and Fall Times with 1nF Output Load Trimmed Timing Capacitor Discharge Current for Accurate
