The LM2660M/NOPB is a versatile switch mode charge pump voltage converter manufactured by Texas Instruments. This component is designed to efficiently manage power within a circuit by converting a positive voltage in the range of 1.5V to 5.5V to either a doubled positive output, an inverted negative output, or a split supply output. Its flexibility makes it an ideal choice for a variety of applications, including battery-powered devices, handheld equipment, and portable consumer electronics.

Key Features

• Voltage Conversion Range: Capable of operating with an input voltage from 1.5V to 5.5V, making it suitable for low voltage applications.
• High Efficiency: Utilizes a switch mode (also known as switched-capacitor) technique, providing a more efficient alternative to linear voltage conversion methods.
• Output Current: Delivers up to 200 mA of output current, depending on the voltage conversion mode and input/output voltage levels.
• Versatile Output Configurations: Can be configured to provide a positive voltage doubling, negative voltage inversion, or split supply for versatile circuit design options.
• Minimal External Components: Requires only two low-cost capacitors for the voltage doubling and inverting functions, reducing the overall materials cost and board space.
• Frequency Operation: Operates at a high switching frequency of 160 kHz, allowing for smaller external capacitors and reduced ripple.
• Thermal and Overcurrent Protection: Features built-in thermal shutdown and overcurrent protection to safeguard the device and the system under extreme conditions.
• Surface Mount Package: Offered in an SOP (Small Outline Package), the LM2660M/NOPB is designed for space-constrained applications.
• Lead-Free and RoHS Compliant: The NOPB (No Lead (Pb)) designation indicates that the product is compliant with the RoHS directive, making it suitable for use in applications where environmental concerns are paramount.
