| Boost-buck for pump |

Morning all, Would anyone happen to know of a suitable series of boost-buck converters which will take in 22-34VDC and output 24V @ 2.5A. Digi-Key is not being my friend on this one. Best regards, Andy Cooke |

Beware, buck-boost can refer to two different topologies. Inverting: the output polarity is opposite to the input. It requires two switches, normally a transistor and a diode. Non-inverting: essentially a buck converter, combined with a boost converter, but sharing the same inductor. It requires four switches: normally two transistors and two diodes. https://en.wikipedia.org/wiki/Buck%E2%80%93boost_converter Which one do you want? |
| andrew_c:
Non-inverting would be preferred. Thanks, Andy |

Then SEPIC or "flying inductor" it is. :) Should be modules roundabout that level, not sure about Chinese ready made PCBs, think LT/AD makes a few chips if you want total integration, else any regulator or controller plus support components will do. Tim |

Check if the pump will run at 22V, which it most likely will. Then all you need is a buck converter. |
