| Is there any modern MC34063 part? |

Hi, I wanted to know if there are some newer parts with the Mhz working range, higher voltages and current or internal MOSFETS instead of BJT's. Do we have any option? |

Astonishingly, hysteretic controllers -- terrible as they are -- do still exist. Fortunately, there are zillions of better alternatives! https://imgur.com/a/M1S0DbI Tim |

I mean, if you want modern bad controls, TPS40200 and LM5085 for example exist for some reason. Looks like they feign current... protection, at least, but that's nowhere near as good as actual current control. TPS40211 is much better, more akin to a UC3843, which is, you know, actually current controlled. ;) It's not gonna be directly buck compatible, no. IMHO, it would be foolish to wish for such in a single low-pin IC (I'd dare use the '34063 as a cautionary example of why this is so). Need buck? Just tack on a bootstrap gate driver. Boom. Done. Regulators are also available in a spectrum of voltage ratings, currents, frequencies and topologies. You don't want a universal controller or regulator -- indeed, the market has spoken, diversity carries the day here! Tim |
