DESCRIPTION
The UTC UT2306 is a micropower step-up DC/DC converter ideal for use in small, low voltage, battery-operated systems. The devices operate from a wide input supply range of 1.5V to 8V.
The UTC UT2306-3.3 and UT2306-5.0 generate regulated outputs of 3.3V and 5V and the adjustable UT2306 can deliver output voltages up to 25V.Quiescent current,120 μ A in active mode, decreases to just 10 μ A in shutdown with the low-battery detector still active. Peak switch current, internally set at 1A,can be reduced by adding a single resistor from the ILIM pin to ground. The high speed operation of the UTC UT2306 allows the use of small, surface-mountable inductors and capacitors.
