The LM2687MM is a low noise, regulated switched capacitor voltage inverter designed by Texas Instruments. It operates with an input voltage range of +2.7V to +5.5V and provides an adjustable negative output voltage between -1.5V and -5.2V. This device utilizes a charge pump topology with a typical switching frequency of 100 kHz, enabling it to deliver up to 10mA of output current with low output ripple.
The LM2687MM features a low quiescent current of 500 µA during operation and a shutdown current of 0.05 µA, making it suitable for low-power applications. Its charge pump power efficiency is typically 91% at 10mA load. The device is available in an 8-pin VSSOP package and is designed for surface mount applications.
Key applications include cellular phone power amplifier biasing, interface power supplies, and other low current, low noise negative voltage requirements in handheld instrumentation and portable electronics.
