dc-dc converter
Hi,
this is with reference to the DER20 report for DC_DC Converters, our customer require the design to be executed with the input range of 22V-26V , please help whether this can be achieved,
will be using DPA426R for flyback converter
Thanking You

Hi Nano
Thank You, will consult you once the proto has been built,
and i also have query regarding the DER 136 Design,
we have modified the existing with TOP244PN for 7W for 42V and 160mA , the problem we are facing is that we are not able to set the output cuurent to exactly or close to 160mA, by fine tuning the sense resistor the output current is either too low or high, please suggest the changes that we can tweak at the output side , so that precision current setting is possible , please note that the output transistor circuit we taken it as same , but the only change we made is with current sense resistor,
please help me in this regards,
Thanking Yoiu
Hi Vivek,
Since this query belongs to another project would you please raise another question in the forum.

Hi,
With 22V-26V input voltage range DPA426R can deliver up to a maximum of 45W when it is used in flyback configuration. If you can configure this to a forward topology then DPA426 can deliver rated 60W at the specified input voltage.
