| Boost-Buck Converters and a reference pin |
| (1/1) |
| roogadget:
I have spent a great amount of time looking for a buck boost converter that outputs 12V. Turns out it requires an external reference of 5V for the PG pin. Do these regulators always require a reference? It seems odd to a beginner (me) that it would require an additional regulator just to use one. |

From the data sheet: --- Quote ---PS 7 I D Logic-level input signal to enable and disable low-power mode. The power mode is low-power mode when this pin is high (1) and is normal mode when this pin is low (1). --- End quote --- So seems to me that if you're not interested in low-power mode, you can just tie that pin to ground. |

PG 15 O D Output power good pin. This pin is an open-drain pin. The status of the power-good output is good when this pin is high (1) and has a failure when this pin is low (0) If you don't need PGOOD, just ignore that pin. |
