TMI3408D

低压Buck转换器; . High Efficiency: Up to 96%. 1.5MHz Constance Frequency Operation. 1.2A Output Current. No Schottky Diode Required. 2.5V to 6V 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. Short Circuit Protection. Thermal Fault Protection. Inrush Current Limit and Soft Start. Input over voltage protection (OVP). <1µA Shutdown Current. DFN2x2-6L Package(2);

The TMI3408D is a constant frequency, current mode PWM step-down converter.  The device integrates 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 TMI3408D can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. 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.
