TMI3408-XX 1.5MHz, 1.2A Synchronous Step-Down Converter with Fixed Output Voltage
●The TMI3408-XX series are fixed output voltage, constant frequency, current mode PWM step-down converters. The devices integrate a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.
■FEATURES:
●High Efficiency: Up to 96%(@3.3V)
●1.5MHz Constant Frequency Operation
●1.2A Output Current
