DESCRIPTION

NAME

NO.

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

C3

I

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).

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
