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 300 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.
FEAT URES
* 0.8V start-up voltage
