QW-R103-029,A

MICROPOWER DC/DC

CONVERTERS WITH

LOW-BATTERY DETECTOR

ACTIVE IN SHUTDOWN

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.

FEATURES

*5V at 200mA from two cells.

*10μA quiescent current in shutdown.

*Operates with VIN as low as1.5V

*Low battery detector active in shutdown

*Low switch VCESAT:370mV at 1A typical.

*120μA quiescent current in active mode.

*Switching frequency up to 300kHz

*Programmable peak current with one resistor.
