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
