Regulated switched-capacitor doubler produces low-noise output voltage

24-07-2015 | Mouser Electronics | Power

Mouser now stocks the Texas Instruments (TI) LM2775, a 5V switched-capacitor 5V boost converter - a regulated switched-capacitor doubler that produces a low-noise output voltage for applications such as USB OTG, HDMI power and portable electronics. The LM2775 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 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.
