In some applications, it is important to reduce quiescent current during low power mode such as start up or burst. The LPM pin reduces the quiescent current to support low power modes. When LPM is pulled low, the buck-boost converter stops to operate and reduce additional power loss, and the supply current in the low-power mode is typically 80 µA. Figure 17 indicates the low power mode operation. Once it is activated, VNEG will drop gradually and FAULT will become high. Only after the LPM deactivates, the buck-boost converter will start up to build the VNEG, and LMG341xR050 will be ready to operate within 1 ms.
