The LM2662M/NOPB is an integrated circuit (IC) component that belongs to the LM2662 family of low-power charge pumps. It serves as a voltage inverter or doubler, generating a negative voltage from a positive input voltage. Here, we present an overview and key features of this IC component.
The LM2662M/NOPB is manufactured by Texas Instruments and is designed for various applications, including portable electronics, battery-powered devices, and remote sensor systems. It offers a cost-effective solution for obtaining negative voltages without requiring bulky or expensive transformers.
One of the key features of the LM2662M/NOPB is its low quiescent current consumption, typically around 50 microamperes. This makes it highly suitable for battery-powered applications, as it minimizes power drain and extends battery life. Additionally, the IC's low operating voltage range, from 1.5V to 10V, ensures compatibility with a wide range of power sources.
The LM2662M/NOPB can generate a negative voltage output that is either equal in magnitude to the input voltage or double the magnitude of the input voltage. This versatility makes it particularly useful in applications that require a negative voltage supply, such as LCD biasing or generating split power supplies. The IC can deliver an output current of up to 40mA, allowing it to power multiple components simultaneously
