Point of load conversion Communications and networking equipment Industrial and instrumentation Consumer electronics Medical applications GENERAL DESCRIPTION
Under light load conditions, they can be configured to operate in a pulse frequency modulation (PFM) mode, which reduces switching frequency to save power. The output voltage can be adjusted from 0.6 V up to the input voltage (VIN) for the adjustable version, whereas the fixed output version is available in preset output voltage options of 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, and 1.0 V.
