LM2775/LM2775-Q1 Switched Capacitor Converter

Texas Instruments LM2775/LM2775-Q1 Switched Capacitor 5V Boost Converter is a regulated switched-capacitor doubler that produces a low-noise output voltage. The LM2775/LM2775-Q1 from Texas Instruments can supply up to 200mA of output current over a 3.1V to 5.5V input range. It can also supply up to 125mA of output current when the input voltage is as low as 2.7V. At low output currents, the LM2775/LM2775-Q1 can reduce its quiescent current by operating in a pulse frequency modulation (PFM) mode. PFM mode can be enabled or disabled by driving the PFM pin to high or low. When the LM2775 is in shutdown, the user can choose to have the output voltage pulled to GND or left in a high impedance state by setting the OUTDIS pin high or low. The LM2775-Q1 devices are AEC-Q100 qualified for automotive applications.
