7.4 Device Functional Modes

7.4.1 Shutdown

The LM2775 enters Shutdown Mode if one of the two conditions are met.

•

•

In Shutdown, the LM2775 typically draws less than 1 µA from the supply. Depending on the state of the OUTDIS

pin, the output is pulled low when entering shutdown (OUTDIS = '1'), or it remains near the final output voltage

with the output in a low leakage state (OUTDIS = '0').

7.4.2 Boost Mode

Depending on the state of the PFM pin, the LM2775 either regulates the output via a PFM burst mode (PFM =

'1') or via a constant switching mode (PFM = '0').
