Other Parts Discussed in Thread: TPS65023

Hi 

 

 

 I need a Power management IC.My requirement is as follows. Can you please suggest a suitable single chip TI part?
Number of Channels required-6 (4 DCDC Converters+2 LDOs)
  1. DCDC1 Output-Fixed or adjustable to 1.35V/1A for DM365 processor
  2. DCDC2 Output-Fixed or adjustable to 3.3V/2A for System power
  3. DCDC3 Output-Fixed or adjustable to 1.8V/1A for DDR
  4. DCDC4 Output-Fixed or adjustable to 3.3V/1.5A
  5. LDO1 Output-Fixed or adjustable to 2.8V/200mA
  6. LDO2 Output-Fixed or adjustable to 2.8V/200mA

                                              OR

Is it possible to get 6 channel (3 DCDC Converters+3 LDOs) with above specification?

    At power.ti.com there is a processor power search.  Simply find your processor and single chip solutions and/or reference designs will appear for that processor.

    With your high currents (in the amps), a single chip IC for all of the above is very hard to come by.  I would recommend picking a smaller PMU just for your DSP and then having a separate power system for the rest of your board.  How about the TPS65023?
