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 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
