LM2757 Product details

Description

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.

Features

are also included in this device. Features.
Inductorless solution uses only 4 small ceramic.
capacitors. True input-output and output-input disconnect. Up to 180 mA output current capability (5V). Selectable 4.1V, 4.5V or 5.0V output. Pre-regulation minimizes input current ripple. 1.24 MHz switching frequency for a low-noise, low-ripple output voltage. Efficient dual gain converter (2X, 3/2X). Integrated Over Current Protection. Integrat.
