Product details

3 A, 52 kHz buck regulator with 60 V input ceiling

The 52 kHz switching frequency keeps EMI manageable and allows the use of larger, lower-cost magnetics — a trade-off that suits industrial and automotive power stages where board space is less constrained than conducted emissions budget.

60 V input, 3 A output — thermal and transient headroom

Rated for a 60 V maximum input, this part handles 48 V industrial rails and 24 V automotive systems with margin for load-dump transients. No synchronous rectifier is integrated — the external Schottky diode adds a conduction loss term that must be factored into the thermal budget.
