BP C3 I This is the mode selection pin of the device and is only of relevance when the device is disabled (EN = Low). This pin must not be left floating and must be terminated. Refer to Table 2 for more details. BP = Low: The device is in true shutdown mode. BP = High: The output is biased at the input voltage level with a maximum load current capability of ca. 150mA. In standby mode, the device only consumes a standby current of 21µA (typ). EN B3 I This is the enable pin of the device. Connecting this pin to ground forces the device into shutdown mode. Pulling this pin high enables the device. This pin must not be left floating and must be terminated. GND C1, C2 Ground pin. SW B1, B2 I/O This is the switch pin of the converter and is connected to the drain of the internal Power MOSFETs. VIN A3 I Power supply input. VOUT A1, A2 O Boost converter output. |
