Needless to say this creates 'issues'!Īnyone here used this part and care to comment? Regds, Graham. The low side drive activates at about 8V and the high side about a volt higher. Indeed a careful look at the data sheet does indeed show that there's no connection. I checked it carefully today and the UVLO for the low side and high side aren't linked. I realised that it happened a couple of times when I wound down the input volts ( I'm supplying the board via a variac and isolating transfomer for development ). I've had some 'odd' power device failures that I didn't expect in entirely benign situations, such as the half bridge output simply driving the primary of my transformer. Hi all, I'm using an IR2110 high and low side gate driver in a smps that I mentioned some time back in the group under the thread 'should I use a SG3525'. PONTE H COM MOSFET E IR2110 - Duration: 0:54. Switch Mode Power Supply Circuit Sg3525 Ir2110 900w Smps Glow Plug Driver With Sg3524 H Bridge Inverter Power Stage With Passives Circuits Diy. Hi, folks So I have two identical half bridge smps, each uses two mosfets and one IR2110 which drives the mosftets, both IR2110 are powered from a. I built it using the exact same parts written in the schematic. Hello everyone, I made a 50Khz SMPS using the schematic I have attached to my message.
