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

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.
