Typical Application DESCRIPTION The TPS8269x SIP device is a plete 500m A, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional ponents are required to finish the design. The TPS8269x SIP is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The Micro SIP™ DC/DC converter operates at a regulated 4-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current...
