Synchronous buck converter IC

USB & power interfaces · 36 V · 8 A · FB 1.25 V

Synchronous buck controller with both MOSFETs inside (averaged model: the switch node is duty × VIN) · 4.5–36 V in · 8 A current limit · regulates FB to 1.25 V · 2 ms soft start · 95 % efficient

Try it on the benchThe lab drops it on an empty bench and opens its datasheet card.
