0.95 V starting DC-to-DC converter
with low battery indicator
TEA1200TS
QUICK REFERENCE DATA
Note
1.
The undervoltage lockout level shows wide specification limits since it decreases with increasing temperature. When
the temperature increases, the minimum supply voltage of the digital control part of the IC decreases and therefore
the correct operation of this function is guaranteed over the whole temperature range. The undervoltage lockout level
is measured at pin UPOUT/DNIN.
