ISL78219 - Automotive Boost Regulator
DATASHEET ISL78219 Automotive Boost Regulator with 4A Integrated Switch FN8941 Rev.0.00 Mar 22, 2018 The ISL78219 is a high frequency, high efficiency current-mode control non-synchronous step-up voltage regulator operated at a constant PWM switching frequency.
It has an internal 4.0A, 120mΩ low-side MOSFET and can deliver high output current and efficiency over 90%.
The selectable 640kHz and 1.22MHz switching frequencies provide faster transient response and allow the use of a smaller induct
ISL78219 Features
* along with higher switching frequency, allow use of tiny external components and minimize the overall PCB footprint. The ISL78219 is available in a 10 Ld TDFN package with a maximum height of 0.8mm. The device is offered for AEC-Q100
