    Hello Jeon,

    Please go to the Power Management page on TI.com: http://www.ti.com/lsds/ti/analog/powermanagement/power_portal.page , input your parameters, click SEARCH.  You will see a list of devices that can be used.  Since you stated dc/dc converter, you can further refine the list by clicking on the INTEGRATED SWITCH UltraLowPower/COMPARE, you will then see the TPS62740 highlighted, along with a list of other devices that could be used.  You can further refine your selection from this point, or invoke a WEBENCH design with the TPS62740 by clicking on the Tools&Software tab.

    Let us know if you need further assistance.

    At your service,

    ~Leonard

    For a wearable, either TPS62743 or TPS82740B are very small solutions.

    It's not clear what you mean by 5V at 15 mA. If this is your input source's capability, it is greater than your required output power. This is not possible.
