LM2760
3.3V Regulated Switched Capacitor Voltage Converter
General Description
The LM2760 is a switched-capacitor DC/DC converter that
generates a regulated 3.3V output capable of driving a load
up to 20mA (V
≥
2.5V). The wide input voltage range
(2.0V-4.4V) allows this device to be powered from several
types of batteries, including single cell lithium-ion, two-cell
alkaline, nickel-metal-hydride, and nickel-cadmium. The
LM2760 solution does not require an inductor and needs
only three small external ceramic capacitors. The miniscule
quiescent current of the part, typically 10μA unloaded,
makes the LM2760 ideal for low-current standby power rails.
The LM2760 is a switched-capacitor circuit that is controlled
by a gated oscillator. Both a low-input-voltage boost mode
and high-input-voltage pass mode are implemented to opti-
mize efficiency over the full input voltage range.
Additional features of the LM2760 include thermal protection
and current limiting. The LM2760 is available in a small,
five-pin SOT-23 package.
