The kB3310 is a MicroPower switched capacitor

voltage converter that delivers a regulated output. No

external inductor is required for operation.

The kB3310 can deliver up to 150mA to the voltage

regulated output. It features very low quiescent current

and high efficiency over a large portion of its load range,

making

this

device

ideal

for

battery-powered

applications. Furthermore, the combination of few

external components and small package size keeps the

total

converter

board

area

to

a

minimum

in

space-restricted applications.

The kB3310 uses a pulse skipping technique to provide

a regulated output from a varying input supply. The

kB3310 contains a thermal management circuit to

protect the device under continuous output short-circuit

conditions.

The kB3310 has lead (Pb) free SOT23-6 package and is

rated over the -30°C to +85°C temperature range.
