Confidential ACT88430 Advanced PMU for Microcontrollers and Solid State Drive Applications ® Startup VIN LDO1 LDO2 Buck1 Buck4 Buck3 nRESET_AUX1 Buck2 713us 713us 513us 513us 713us 2ms CMI 109 Startup SLEEP Mode Pull PWREN high to operate in ACTIVE mode. Pull PWREN low to operate in SLEEP. Outputs Buck1/3/4 are on in ACTIVE mode and off in SLEEP mode. DVS Mode PWREN is the DVS control input for Buck2. When PWREN = L, the VSET0 register controls the Buck2 converter output voltage to 0.75V. When PWREN = H the VSET1 register controls the Buck2 converter output voltage to 0.9V. EXT_PG is the DVS control input for Buck3. When EXT_PG = L, the VSET0 register controls the Buck3 converter output voltage to 1.5V. When EXT_PG = H the VSET1 register controls the Buck3 converter output voltage to 1.35V. GPIO is the DVS control input for Buck4. When DVS = L, the VSET1 register controls the Buck4 converter output voltage to 1.8V. When GPIO = H the VSET0 register controls the Buck4 converter output voltage to 1.2V. POK Thresholds POK_UV = 2.77V POK_OV = 3.76V PG The PG pin is configured as the Buck3 POK output. POK The POK pin is configured as the VIN POK functionality. EXT_EN The EXT_EN pin is not functional with CMI 109. Leave the EXT_EN pin floating. nRESET |
