LM2760 3.3V Regulated Switched Capacitor Voltage Converter LM2760 OBSOLETE September 23, 2011 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 (VIN ≥ 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.
