The LM5177 is a four switch buck-boost controller. The device provides a regulated output voltage if the input voltage is higher, equal, or lower than the adjusted output voltage. In power save mode, the device supports high efficiency with low output loads due to its low quiescence currents. The LM5177 runs at a fixed switching frequency, which can be set through the RT or SYNC pin. The switching frequency remains the same during buck, boost, and buck-boost operation. The integrated and optional average current monitor can help monitor and limit input and output current of the LM5177. This feature also supports charging backup power elements, like batteries or capacitors, with constant current (CC) and constant voltage (CV).
