voltage rating is not enough, u also need to provide the load current continuous, peak and average. For anything less than equal to 1A, u can use the boost converter IC from different manufacturer like NI, linear tech, analog devices etc. U can get the complete part selection from their respective websites.
For currents more than few amperes, usually a separate boost converter is used with MCU to control switching cycle. U can designs from google. microchip.com has several reference designs and application notes for boost, buck and flyback converters with complete design guide.
