ISL78219ARTZ

The ISL78219ARTZ-T7A 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 ISL78219ARTZ-T7A draws current at <1μA and can operate at as low as 2.3V input. These features, along with higher switching frequency, allow use of tiny external components and minimize the overall PCB footprint.The ISL78219ARTZ-T7A is available in a 10 Ld TDFN package with a maximum height of 0.8mm. The device is offered for AEC-Q100 Grade 2 operation with an ambient temperature range of -40°C to +105°C.
