TMI3113B

低壓Buck轉(zhuǎn)換器; . High Efficiency: Up to 95%. 1.0MHz Constant Frequency Operation. Up to 3A Output Current. No Schottky Diode Required. 2.7V to 5.5V Input Voltage Range. Output Voltage as Low as 0.6V. PFM Mode for High Efficiency in Light Load. 100% Duty Cycle in Dropout Operation. Low Quiescent Current: 50μA. Short Circuit Protection. Thermal Fault Protection. Power Good Output Function (TMI3113 only). Inrush Current Limit and Soft Start. Input overvoltage protection (OVP). <1μA Shutdown Current. TSOT23-6 package for TMI3113. SOT23-5 package for TMI3113B(2);

The TMI3113 and TMI3113B are 1.0MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring high output current up to 3A from single-cell Lithium-ion batteries. They also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications. The high switching frequency of TMI3113/TMI3113B could?minimize the size of external components while keeping switching losses low. The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation. TMI3113 has power good function and it is offered in 6 pin, TSOT23-6 package. The TMI3113B?is offered in 5-pin, SOT23-5 package with adjustable output voltage without PG pin.These devices offer two operation modes, PWM control and PFM Mode switching control, which allow a high efficiency over the wider range of the load.
