1.25MHz, 1.5A Step-Down Switching Regulator 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 www.DataSheet4U.com & instantaneous duty cycle adjustment as the input varies (ideal for CPE applications where the input is a wall plug power). applications where battery life is important.
