Active 500 mA synchronous buck in TSOT-23-5
The MAX8560EZK+T: Switching at 4 MHz allows the use of small inductors and ceramic capacitors, keeping the total solution footprint compact for space-constrained portable or battery-powered designs.
Housed in a TSOT-23-5 (SOT-23-5 Thin) package, the MAX8560EZK+T occupies minimal PCB real estate. The five-pin footprint includes the switch node, feedback, and enable pins — a standard layout for small buck converters. ROHS3 compliance covers current EU and global material restrictions, simplifying compliance documentation for the BOM.
Sourcing and compliance posture
No official pin-compatible second source or direct replacement is listed by the manufacturer. If dual-sourcing is required, a parametric search for 500 mA synchronous buck converters in TSOT-23-5 with a 4 MHz switching frequency will yield functional alternatives, but each requires a BOM review of the feedback network and enable logic.
