LM2757 Product details

Description

The LM2757 is a constant-frequency pre-regulated switched-capacitor charge pump that operates at 1.25 MHz to produce a low-noise regulated output voltage.

Features

1 Dual Gain Converter (2×, 3/2×) With up to 93% Efficiency.
Inductorless Solution Uses Only 4 Small Ceramic Capacitors.
Total Solution Area < 12 mm2.
True Input-Output and Output-Input Disconnect.
Up to 180-mA Output Current Capability (5 V).
Selectable 4.1-V, 4.5-V or 5-V Output.
Pre-Regulation Minimizes Input Current Ripple.
1.24-MHz Switching Frequency for Low-Noise, Low-Ripple Output Voltage.
Integrated Overcurr.
