The TPS6274x are the first buck converters in the industry with input voltages ranging from 2.2V to 5.5V with typ characteristics. 360 na quiescent current and operating ?Typ. 360 na quiescent current with small 2.2µh inductor and 10µf output capacitor. ? 90% Efficiency 10μA Output Current This new dcs control based ? device extends the light load efficiency below the 10μA load current range. TPS62740 supports up to 300mA output current, (TPS62740/TPS62742) TPS62742 supports up to 400mA output current. The device consists of ?RF-friendly dc-control TM rechargeable lithium-ion batteries, li-primary batteries, Li-SOCl2, Li-MnO2, 2- or 3-cell alkaline batteries, and other chemistries with a 2 MHz switching frequency. Input voltage range ? Low output ripple voltage up to 5.5V, also allows operation from USB port and ? 16 selectable output voltages in 100mV steps for thin film solar modules. The output voltage is user 1.8 ~ 3.3V, selectable by 4 VSEL pins, 100mV automatic transition to no ripple 100% mode 1.8 ~ 3.3V. The TPS6274x feature low output ripple voltage and low noise, and switch output capacitors with small rotational speed control loads. Once the battery voltage? The discharge function output voltage/load is close to the output voltage (duty cycle is close to 100%)? The power is good and the output device enters 100% without ripple? The optimized operation mode operates as small as 2.2μh to prevent the increase of the output ripple voltage. The device then stops switching and the output isInductor and 10µf COUT is connected to the input voltage. Integrated rotary? Total solution size <31mm2 rate control load switch provided typ. 0.6?? Small 2 x 3 mm2 WSON pack resistance, can temporarily use the subsystem for the selected output voltage. 2 applications TPS6274x is available in a small 12-pin 2×3mm2 WSON package, supporting total solution size?
