Two independent converters in a single 32-QFN (5x5 mm) package shrink the footprint of a two-rail point-of-load supply. ## Switching frequency — inductor size vs. efficiency trade-off The 300 kHz to 2 MHz switching range is a design lever. At the low end you get better efficiency but need a physically larger inductor. At 2 MHz the inductor shrinks to a smaller footprint, useful when board area is tight. ## Temperature grade and environment Rated for -40°C to 105°C ambient, this part fits industrial and automotive cabin/chassis environments. The exposed pad on the 32-QFN (5x5 mm) must be soldered to a thermal land on the PCB. ## Lifecycle and compliance The ISL78208ARZ-T7A carries an Active product status and is ROHS3 compliant.","metaTitle":"ISL78208ARZ-T7A Dual 3A Buck Regulator, 28V Input, QFN","metaDescription":"Renesas ISL78208ARZ-T7A dual 3A adjustable step-down regulator. 4.5V-28V input, 300kHz-2MHz switching, -40°C to 105°C.
