The LM2662MX/NOPB is a high performance voltage inverter and voltage doubler integrated circuit (IC) component manufactured by Texas Instruments. It is designed to generate a regulated negative voltage from an input positive voltage or to double an input voltage. The IC operates with a wide range of input voltages, making it suitable for various applications.
One of the key features of the LM2662MX/NOPB is its ability to provide a regulated negative voltage output. It can generate a negative voltage that is typically equal to -VIN. This negative output voltage is regulated, ensuring a stable power supply for connected circuitry. This feature is particularly useful in situations where a negative voltage rail is required, such as in some operational amplifiers or LCD displays.
Another noteworthy feature is the IC's voltage doubler functionality. When the input voltage is applied, the LM2662MX/NOPB can double it to provide a positive voltage output. This feature eliminates the need for an external transformer or inductor and reduces the complexity of the power supply circuitry. It is suitable for applications where a higher voltage level is required, such as in driving capacitive loads or powering analog-to-digital converters.
The LM2662MX/NOPB also offers a wide input voltage range, allowing it to operate with input voltages ranging from 2.2V to 5.5V. This makes it compatible with a variety of power sources, including batteries and other low voltage power supplies
