The wettable-flank option lets AOI verify the solder joints on the side — no X-ray needed for the QFN hidden pads. The exposed pad under the IC is the primary thermal path. The datasheet layout guide recommends a thermal-via array under the pad tied to the ground plane — without it the junction-to-board thermal resistance rises and the 125°C Tj ceiling gets tight under full load. ## Dual synchronous buck-boost — 6 V to 42 V input, 2 outputs This is a dual synchronous buck-boost controller — two outputs, one phase each, transistor-driver output type. It steps up or down from a 6 V to 42 V supply rail, switching between 200 kHz and 2.2 MHz with clock-sync capability. The 98.75% max duty cycle means the high-side FET stays on nearly the whole cycle — useful when the input voltage dips close to the output, like a cold-crank event on a 12 V automotive bus. Synchronous rectification is built in, so the low-side FET is actively driven rather than relying on the body diode — cuts the rectification loss and keeps the efficiency curve flatter across the load range. ## Automotive temp grade — under-hood margin That is the full automotive Grade 1 temperature band — the controller survives the under-hood ambient on a hot engine bay summer day without derating.","metaTitle":"ISL78263ARZ-T7A Renesas Dual Buck-Boost Controller, AEC-Q100","metaDescription":"Renesas ISL78263ARZ-T7A dual synchronous buck-boost controller, 6-42V input, 200kHz-2.2MHz, AEC-Q100 automotive grade.
