MAX16993 replacement

Other Parts Discussed in Thread: TPS65261, TPS54302, LM53635-Q1

Hi Sir,

I am looking for a device to replace MAX16993. I got the information from TI web cross reference that TPS65261 has similar functionality with MAX16993. I need a device which can support higher input voltage up to 28V. Does TI have any suitable solutions? Single chip or discrete solution (two chips) are ok for me.

Thanks!

MAX16963 looks like for automotive application, 36V input, up to 2.1MHz switching freqeuncy and 3A IOUT. For our Power/MCP, only 28V parts like TPS54302 output 3A, but only 400kHz switching frequency. Maybe you can check like LM53535-Q1 from SVA team.

MAX16993 is a 3ch DC to DC converter. CH2 and CH3 are cascaded from CH1. TPS54302 is a single channel buck converter. I need three supplies and need adjustable switching frequency function.
BTW, I cannot find LM53535-Q1 from TI website.

Thanks!
