HIGH PERFORMANCE SYNCHRONOUS BUCK CONTROLLER WITH LDO FOR PORTABLE POWER November 21, 2000 SC1401 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1401 is a synchronous buck regulator designed to power the latest generation microprocessors in battery operated systems. The SC1401 may be used to provide both the I/O and core voltages utilizing synchronous rectification for the core supply voltage and an LDO N-Channel MOSFET controller for the I/O supply voltage. A 1.25 volt reference allows lower output voltages required by today’s portable microprocessors. The synchronous buck regulator is capable of achieving efficiencies up to 95%. The gate drive circuitry can deliver 2.
