I have question for TPS65910 and DSP DM3725 system.
I checked for TPS65910 Boot mode Spec
TPS65910 recomeded Boot 0 [ 1 ] , Boor1 [ 0 ] for DM3725.
VDD1 spec is 1.2V (Typ) by Boot [ 1:0 ] ( = 01 ) *About VDD2 same as VDD1 Voltage 1.2V.
But I checked DM3725 OPP100 Max spec, About this MAX voltage 1.2V.
I have question
Q1 : Dose TPS65910 Boot [0:1] (= 1 0 ) VDD 1.2V is noplobrem for DM3725?
Q2 : I think Abou this VDD_1/ VDD_2 Voltage cgabge by Automatic "Smart Rflex" .
Dose Voltage change by automatic with TPS65910?
Q3 : If dose not change VDD_1 / VDD_2 by Automatic ,
This cause is " Dose not Work Smart Rflex Mode ? " ??
Q4 : VDD1 Power currnet is very small, Now this Power working PFM mode with 80mV swing SW mode.
Is this PFM mode is OK ?
I waiting answer .
Thanks and Regard
Q1: It does not seem to be a problem.
I am not sure to understand what you mean in Q2 and Q3, could you please be more specific?
Q4: PFM mode is enabled in EEPROM config : DCDCCTRL_REG.VDD1_PSKIP. The transition between PWM and PSM mode is automatic.
