Included in the package are the switching regulator, inductor and input/output capacitors. Integration of all passive ponents enables a tiny solution size of only 6.7mm2. . Typical Application TPS8268180SIP VBAT CI MODE pin; tie to VIN ENABLE DC/DC Converter MODE EN FB GND VOUT 1.80V / up to 1.6A The TPS8268x is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications in which high load currents in a very small solution size and height are required. The TPS8268x is optimized for high efficiency and low output voltage ripple and supports up to 1600-m A load current. With an input voltage range of 2.5-V to 5.5-V, the device supports applications powered by Li-Ion batteries as well as 5V and 3.3-V rails. The TPS8268x operates at a 5.5-MHz switching frequency with spread spectrum capability. For noisesensitive applications, this provides a lower noise regulated output, as well as low noise at the input. The device supports a fixed output voltage, requiring no external feedback...
