DESCRIPTION
The L4963 is a monolithic power switching regulator
delivering 1.5A at 5.1V. The output voltage is adjust-
able from 5.1V to 36V, working in discontinuous
variable frequency mode. Features of the device
include remote inhibit, internal current limiting and
thermal protection, reset and power fail outputs for
microprocessor.
