UC3500

HIGH EFFICIENCY VFM CONTROLLED STEP-UP ?DC/DC CONVERTER; · 0.8V start-up voltage \n· 0.5V hold-on voltage \n· Output current up to 150mA \n· Low supply current of 18μA \n· Wide output voltage range of 2.5V~5.5V \n· Output voltage accuracy ±2% \n· High efficiency up to 88% \n· Low profile and minimum external components;

The UTC UC3500 Step-up DC/DC converters are optimized for applications that prioritize high efficiency and high frequency. The efficiency is greatly improved by utilizing an internal VFM controlled scheme that switches with fixed frequency and is adjustable up to more than 150 KHz depending on the load. The UTC UC3500 requires only three external components to realize the conversion from the battery voltage to the selected output voltage in the range of 2.5V ~ 5.5V. The start-up voltage of UTC UC3500 is guaranteed at 0.8V and the device is operating down to 0.5V. The Output current is guaranteed up to 150mA, while quiescent current is only 18μA.
