High Performance Synchronous Buck Controller With Ldo For Portable Power

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 todays portable Microprocessors The synchronous buck Regulator is capable of achieving efficiencies up to 95%. The Gate drive circuitry CAN deliver 2.0A peak currents, allowing the use of N-Channel MOSFETs for lower switching and conduction losses. A digital soft start is provided to ensure orderly start up of the power supply without the need for external components. At light load in power save mode, the controller changes mode of operation by missing Gate drive cycles, thus reducing Gate drive current and improving efficiency. A Logic high on PSAVE disables the power saving mode thus reducing noise. The By Semtech Corporation
