Products Overview

High-Efficiency EZBuck Synchronous Regulators

Alpha and Omega Semiconductor

Alpha and Omega’s regulators feature multiple protection functions such as output overvoltage protection, short-circuit protection, and thermal shutdown

The EZBuck synchronous regulators feature multiple protection functions such as VCC under-voltage lockout, cycle-by-cycle current limit, output overvoltage protection, short-circuit protection, and thermal shutdown. Several families are offered in QFN 3x3, 4x4, 5x5, DFN 3x3, TSOT23-6L and EPAD SO-8 packages making them ideal for industrial, telecom, and networking equipment.
