Part Details:

LM2760 December 2002 3.3V LM27603.3V Regulated Switched Capacitor Voltage Converter Regulated General Description Features The LM2760 is a switched-capacitor DC/DC converter that n 3.3V ± 4% Regulated Output generates a regulated 3.3V output capable of driving a load n Ultralow Power: 10µA Typical Supply Current up to 20mA (V 2.5V). The wide input voltage range IN n Boost and Pass Modes for Improved Efficiency (2.0V-4.4V) allows this device to be powered from several n Input Voltage Range: 2.0V to 4.4V types of batteries, including single cell lithium-ion, two-cell n Output Current up to 20mA (V 2.5V) Switched IN alkaline, nickel-metal-hydride, and nickel-cadmium. The n Output Current up to 10mA (V 2.0V) LM2760 solution does not require an inductor and needs IN only three small external ceramic capacitors. The miniscule n Inductorless solution quiescent current of the part, typically 10µA unloaded, n Small external parts count: 3 ceramic capacitors makes the LM2760 ideal for low-current standby power rails. n 750kHz Switching Frequency The LM2760 is a switched-capacitor circuit that is controlled n SOT23-5 Package by a gated oscillator. Both a low-input-voltage boost mode n Short-Circuit and Thermal Protection Capacitor and high-input-voltage pass mode are implemented to opti-mize efficiency over the full input voltage range. Applications Additional features of the LM2760 include thermal protection n Battery-Operated Devices and current limiting. The LM2760 is available in a small, n Cellular Phone five-pin SOT-23 package. n Standby Power Supply n Memory Keep-alive Power Voltage Typical Application Circuit Converter 20044301 © 2002 National Semiconductor Corporation DS200443
