I want to use MOSFET driver IRS2110 to ...Hi Tahmid,<br />I want to use MOSFET driver IRS2110 to drive MOSFET IRF 540N in power supply design.<br />MOSFET switching frequency, I want to keep 20 kHZ. I am obtaining the gating signal using dSpace 1104.<br />I have gone through your blog (Using the high-low side driver IR2110).Still I have few question regarding IRS2110.Please help me to answer these questions based on your experience.<br />1. Is there any difference between IR 2110 or IRS 2110.I have IRS 2110 available?<br />2. What is the maximum switching frequency for which IRS 2110 can be used without any distortion of the pulses? Because I can generate upto 100kHz frequency using dSpace 1104.<br />3. As you wrote in your blog that IRS2110 is not an isolated driver. we should connect Vss and COM. What is the harm if we do not connect them?<br />Secondly if I want isolation between input pulse and output pulse,How will I get it in case of low-side switch.<br />4. I have damaged 5-6 IRS2110.I don’t know what was the reason.I tell you the process what I followed.<br />I used the circuit given in Datasheet from IR on PCB.I just applied the same input pulses on Lin and Hin pin and used 0.1uF boost strap capacitor. I didn’t short the Vss and COM (As I was thinking that this driver provides isolation).i used two separate power supplies for VDD (+15V) and VCC (+15V).I saw the ouput pulses on DSO without connecting the pulses to any MOSFET.<br />Initially I got the output pulse with same frequency and amplified magnitude but when I repeated the same test, there were no pulses on these pins.<br />I don’t know, where I was making mistake!! May be it is due to not connecting the output pulses to switch or may be VDD (+15V).<br />Sometime IC also got heated and the VCC supply dropped to 3-4 volt.<br />Please help me what mistake I was making.<br />5. From datasheet it is not clear that where to connect the ground terminal of Hin and Lin pulses. Is it to connect to VSS?<br />6. what should be the boost capacitor value ,if I am using IRF 540N for 20kHz and 20 V output in case of high side driver in zeta converter?<br />7.You used additional diode D2,D3 and resistors R2,R3 (10R),is it having value 10ohm or I may use any value like 100ohm or 1 k, how does it vary? and what kind of diode are they. Can I use signal diode 4148?<br /><br /><br /><br />Please answer me and help.<br />Thanks<br />Man Mohan<br />SONUhttps://www.blogger.com/profile/15874025355900163531noreply@blogger.comtag:blogger.com,1999:blog-6338993703407602171.post-72233584952966618102014-04-08T00:17:44.616-07:002014-04-08T00:17:44.616-07:00I need to learn to design PCB .

Good job Tahmid.<br /> Please, can you do a tutorial on using the ExpressSCH and ExpressPCB in making PCB. Thanks.Eboynoreply@blogger.com
