ISL78219ARTZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78219ARTZ-T7A is an obsolete automotive boost regulator featuring a 4.0A integrated low-side MOSFET with 120mΩ Rds(on). It operates within a +2.3V to +6.0V input voltage range and supports output voltages from 1.1 times the input up to 24V. The device offers selectable switching frequencies of 640kHz or 1.22MHz, achieving high efficiency of 93% at 5V in and 12V out with 0.5A load. It includes adjustable soft-start, internal thermal protection, and draws less than 1μA in shutdown mode. Packaged in a 10-lead TDFN with a maximum height of 0.8mm, it is AEC-Q100 Grade 2 qualified for -40°C to +105°C operation.
