LM2757 - Switched Capacitor Boost Regulator

The LM2757 is a constant frequency pre-regulated switchedcapacitor charge pump that operates at 1.25 MHz to produce a low-noise regulated output voltage. The device can be configured to provide up to 100 mA at 4.1V, 110 mA at 4.5V, or 180 mA at 5V. Excellent efficiency is achieved without the use of.
