Overview
UM1660 Low Power DC/DC Boost Converter UM1660S SOT23-5 UM1660DA DFN6 2.
0×2.
0 General Description The UM1660 is a PFM controlled step-up DC-DC converter with a switching frequency up to 1MHz.
The device is ideal to generate output voltage for small to medium LCD bias supplies and white LED backlight supplies from a single cell Li-Ion battery.
The part can also be used to generate standard 3.
3V/5V to 12V power conversions.
With a high switching frequency of 1MHz, a low profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor.
The UM1660 has an internal 400mA switch current limit, offering lower output voltage ripple.
The low quiescen...
