Tool/software:
Hi,
I am trying to design a constant current source output using TPS54062 (or any other low IQ buck convertor) to drive a coil using an H-bridge.
1) Vin = 24V.
2) Vout < 0.5V.
3) Output Current = 25mA max (settable using Rset resistor).
I am attaching the reference design which uses a different dc/dc convertor but my application is the same. I need to design something similar to this using TPS54062 or any other low IQ buck convertor.
Any help application or design note that can help me get started is greatly appreciated.
