Preliminary Data sheet
SGM3110
MicroPower
Regulated Charge Pump
GENERAL DESCRIPTION
The SGM3110 is a MicroPower switched capacitor
voltage converter that delivers a regulated output. No
external inductor is required for operation.
The SGM3110 can deliver up to 100mA 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 SGM3110 uses a pulse skipping technique to provide
a regulated output from a varying input supply. The
SGM3110 contains a thermal management circuit to
protect the device under continuous output short-circuit
conditions.
The SGM3110 has lead (Pb) free SOT23-6 package and is
rated over the -40°C to +85°C temperature range.
