2019年12月30日 · The 34063's hysteretic behavior makes a huge mess. Tim Wow, I simulated the same circuit at a lower output voltage, higher output current and the efficiency got up to …

2017年3月17日 · The only real advantage of the '34063 - and I suspect the primary reason it has been in continuous production for decades now - is that it is hysteretic mode controller so does …

2020年1月23日 · It made the '34063 model run in bursts with wildly varying pulse widths from cycle to cycle, some of which were way too long (ie - allowing current to build up way too high …

2015年11月14日 · The 34063 is not the most high frequency, efficient, modern device on the market - but I guess it is common and cheap. I got mine from an old automotive USB charger. …

2021年11月4日 · The problem with 34063 is, it fakes it. It has a current sense pin but its effect is to skew the oscillator duty cycle and frequency, it only acts to limit current by coincidence; it …

2019年2月23日 · Don't! Choose a different IC, designed specifically to boost from a single cell LiPO. 700mA @ 12V is 8.4W, which will require more than 2.8A input current at the battery's …

2016年3月19日 · Hello, I am using MC34063 in a voltage boost configuration to boost 3.5V to 5V. Vin: 3.2V Vout: 5V Iout: 375mA Component Values: R: 180 ohms Rsc: 0.22 ohms Cin: 10uF …

2015年1月19日 · Many thanks for the answers guys. You've given me a lot to think about. I did suspect that there might be better ways to go than the MC34063 but I don't have enough …
