ISL78215 Datasheet, PDF (1/11 Pages) Intersil Corporation – Improved Industry Standard Single-Ended Current Mode PWM Controller

Improved Industry Standard Single-Ended Current
Mode PWM Controller
ISL78215
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 fully TS16949 compliant and tested to
AEC-Q100 specifications.
