9 / 20 page STOD2540 Functional description Doc ID 12204 Rev 10 9/20 5.5 Load isolation switch When the device is in shutdown mode, a DC current path always exists between the power source and the load; increasing the standby consumption. A high side switch LDS isolates the load from the source when the STOD2540 is disabled. 5.6 Efficiency The total consumption of some PMOLED display, can be as low as 1 mA. In order to increase the battery run time of the device, STOD2540 offers a high efficiency over a wide range of load and input voltage range. 5.7 Under voltage lockout (UVLO) The minimum supply voltage is 3.0 V, under this value the under voltage lockout circuit operates with typical threshold 2.8 V. When supply voltage is below 3.0 V, possible noise in the supply line could disturb the UVLO circuit causing loss of output regulation. This behavior is eliminated choosing CI = 10 µF or higher. |
