DESCRIPTION

The SP6ꢀ38 is a synchronous step-down switching regulator controller optimized for small

footprint. The part is designed to be especially attractive for single supply step down con-

version from 5V to 24V. The SP6ꢀ38 is designed to drive a pair of external NFETs using a

ﬁxed2.5MHzfrequency, PWMvoltagemodearchitecture. ProtectionfeaturesincludeUVLO,

thermalshutdown, outputshortcircuitprotection, andovercurrentprotectionwithautorestart.

The device also features a PWRGD output and an enable input. The SP6ꢀ38 is available in

a space saving ꢀ6-pin QFN and offers excellent thermal performance.
