POWER MANAGEMENT
Description
The SC4517A is a current mode switching regulator with
an integrated switch, operating at 1.25MHz with separate
sync & enable functions. The integrated switch allows
for cost effective low power solutions (peak switch current
1.5 amps). The sync function allows customers to
synchronize to a faster clock in order to avoid frequency
beating in noise sensitive applications. High frequency
of operation allows for very small passive components.
Current mode operation allows for fast dynamic response
& instantaneous duty cycle adjustment as the input varies
(ideal for CPE applications where the input is a wall plug
power).
