    描述 The LM2773 is a switched capacitor step-down regulator that produces a selectable 1.8V or 1.6V output. It is capable of supplying loads up to 300mA. The LM2773 operates with an input voltage from 2.5V to 5.5V, accommodating 1-cell Li-Ion batteries and chargers. The LM2773 utilizes a regulated charge pump with gains of 2/3x and 1x. It has very low ripple and noise on both the input and output due to its pre-regulated 1.15MHz (typ.) switching frequency and spread spectrum operation. When output currents are low, the LM2773 automatically switches to a low-ripple PFM regulation mode to maintain high efficiency over the entire load range.The LM2773 is available in TI's 0.5mm pitch 9-bump DSBGA.特性Low-Noise Spread Spectrum Operation 1.8V/1.6V Selectable Output Voltage 2% Output Voltage Regulation > 75% Efficiency in 1.8V Mode Very Low Output Ripple: 10mV @ 300mAOutput Currents up to 300mA 2.5V to 5.5V Input Voltage Range Shutdown Disconnects Load from VIN 1.15MHz Switching Frequency No Inductors…Small Solution Size Short Circuit and Thermal Protection 0.5mm pitch, DSBGA-9 (1.511 × 1.511mm × 0.6mm) All trademarks are the property of their respective owners.
