Half-bridge driver for synchronous buck stages
The ADP3120AJRZ is a dual N-channel MOSFET driver configured for half-bridge topologies. It drives two external N-channel MOSFETs with a bootstrap supply up to 35 V.
Input logic thresholds and bootstrap headroom
Logic input thresholds are 0.8 V (VIL) and 2 V (VIH). The bootstrap high-side voltage maximum is 35 V.
Package and mounting
Housed in an 8-SOIC package with a 3.90 mm body width and 0.154" pitch, the ADP3120AJRZ fits standard SOIC-8 land patterns. Surface-mount assembly is straightforward for reflow processes. The supplier device package is listed as 8-SOIC. The part is — no tape-and-reel carrier, so plan for tube or tray handling if your pick-and-place line expects reels.
Lifecycle and compliance
ROHS3 compliant, so it meets current EU and global restriction requirements. No lead (Pb) finish concerns for designs shipping into RoHS-regulated markets. Because it is active, there is no LTB window to track — it remains a viable choice for both new builds and sustaining production.
