The TMI3408 are 1.5MHz constant frequency, current mode 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. The output voltage can be regulated as low as 0.6V. The TMI3408 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. The devices offer 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
●No Schottky Diode Required
●2.5V to 6.0V Input Voltage Range
●Output Voltage as Low as 0.6V
●100% Duty Cycle in Dropout
●Low Quiescent Current: 40μA
●Slope Compensated Current Mode Control for Excellent Line and Load Transient Response
●Soft Start time for 1ms
●Short Circuit Protection with Frequency reduction mode
●Thermal Fault Protection
●Inrush Current Limit and Soft Start
●Input over voltage protection (OVP)
●<1μA Shutdown Current
●Available SOT23-5 and DFN2x2-6L Packages
