98 / 110 page  4 Current consumption Table 78. Mean current consumptions in loop operating mode Symbol Parameter Test condition Min Typ Max Unit ISTBY_VCC1 Current consumption on VCC. No PWM switching. VCC = 5 V -40 °C ≤ Tj ≤ 25 °C Default configuration and VR_EN1 = VR_EN2 = 0 V 50 70 100 mA ISTBY_VCC2 Current consumption on VCC. No PWM switching. VCC = 5 V 25°C ≤ Tj ≤ 150 °C Default configuration and VR_EN1 = VR_EN2 = 0 V 50 70 100 mA Note: • Current consumption on VCC when PWM are switching can be estimated by incrementing the STBY consumption by the extra current needed by the n-th switching PWM buffer to drive the external capacitive load. IPWMn=CLoadfswVREF2 CFILT Where fsw is the phase`s switching frequency and Cload is the input capacitance of DrMOS PWM pin. • Indicated current consumptions include only STPM098C related contribution strictly needed to its functional operation. As a consequence, they do not include consumption due to additional applicative elements connected to the device (example DrMOS REFIN loading, PMBus™ interface pull-up resistances, external resistive partitioning etc.) STPM098C Current consumption DS14440 - Rev 1 page 98/110 |
