YX605 NOLSUOYSWNCISHNRPTOUETNPOH-UIGUSHPSETFCEFPOIC-UINEPNVCCOEYNRVTERETRER V1.0 SYNCHROLOW INPUT HIGH EFFICIENCY FEATURES GENERAL DESCRIPTION  Up to 0.9V Startup Voltage  Up to 94% Efficiency  Internal Power Switch  3.3V and 5V Fixed or Adjustable Output Voltage  Zero Supply Current Shutdown Mode  Tiny SOT 23-5 Package APPLICATIONS  Hand-Held Devices  One to Three Cell Battery Operated Devices  PDAs  Cellular Phones  Digital Cameras  GPS The YX6 0 5 Low Input High Efficiency Synchronous Step-Up Converter is capable of delivering more than 400mA output current using only three external components. Typical startup voltage is 0.95V and the device can operate down to a 0.6V input voltage. Incorporating an internal synchronous rectifier, the YX6 0 5 can achieve high efficiency of up to 94%. Variable switching frequency operation results in high efficiency for a wide range of loads. The output voltage is selectable between 3.3V and 5V, or can be externally set to any voltage between 2V and 5V. The YX6 0 5 is available in the tiny SOT23-5 Package. Figure 1.
