TPS62250

The TPS62250 is a high efficient synchronous step down dc-dc converter optimized for USB powered applications. It provides up to 1A peak output current and limits the average input current to 700mA, making it ideal for applications connected to a USB host. With an wide input voltage range of 2V to 6V, the TPS62250 supports applications powered by the USB host as well as general applications requiring large output capacitors.
 
Features of the TPS62250 are:(1)high efficiency step down converter;(2)max peak current limit of 1A, ideal for USB powered applications;(3)VIN range from 2 V to 6 V for Li-Ion batteries with extended voltage range;(4)2.25 MHz fixed frequency operation;(5)power save mode at light load currents;(6)output voltage accuracy in PWM mode ±1.5%;(7)voltage positioning at light loads;(8)typical 15 mA quiescent current;(9)100% duty cycle for lowest dropout;(10)available in a small 2*2*0,8mm SON package;(11)allows < 1 mm solution height.
