Rev.0.00
Mar 22, 2018 Automotive Boost Regulator with 4A Integrated Switch 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, 120mО© 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 inductor. An
external compensation pin provides flexibility in setting
frequency compensation, allowing the use of low ESR
small ceramic output capacitors.
When in shutdown mode, the ISL78219 draws current at …
