datasheet4u.
com Output in Shutdown General Description The LM2757 is a co nstant frequency pre-regulated switched capacitor charge pump that operates at 1.
25 MHz to produce a low-noise regulat ed output voltage.
The device can be co nfigured to provide up to 100 mA at 4.
1 V, 110 mA at 4.
5V, or 180 mA at 5V.
Exc ellent efficiency is achieved without t he use of an inductor by operating the charge pump in a gain of either 3/2 or 2 according to .
