    boost converter and sleep mode

    prajakta.zagade

      Hello all,

         

      I am doing one project which has controller of cy8c3244pvi-133

         

      I am doing one application where I am using boost converter and sleep mode.

         

      my boost converter works fine if I dont put it in standby mode while entering controller into sleep mode. It works for for Vbat of 1V

         

      but when I put boost converter to sleep mode then I doesnt work for input battery voltage of 2.5V

         

      I am writing following sequence:

         

                  BoostConv_Stop();
                  CyDelay(1);
                  CyPmSaveClocks();        
                  CyDelay(1);
                  BoostConv_SetMode(BoostConv_BOOSTMODE_STANDBY);

              // Entry SLEEP i.e lowest power mode     
                  CyPmSleep(PM_SLEEP_TIME_NONE, PM_SLEEP_SRC_PICU);
                  CyDelayUs(30);

                  BoostConv_SetMode(BoostConv_BOOSTMODE_ACTIVE);
                  CyDelay(1);
                  BoostConv_Start();
                  CyDelay(1);
                  BoostConv_SelExtClk(BoostConv__EXTCLK_ILO);
                  CyDelay(1);
                 
               // Restore clock tree configuration
                  CyPmRestoreClocks();
                  CyDelay(1);

         

      please guide me
