Description
The MAX660MX/NOPB is a CMOS charge-pump voltage converter manufactured by Texas Instruments. It is designed to invert or double input voltages with a minimal number of external components, making it suitable for applications requiring efficient voltage conversion. Operating over a 1.5V to 5.5V input voltage range, it can deliver output currents up to 100mA. The device operates at a frequency of 10kHz to 100kHz, helping to minimize both power consumption and output ripple.
Key features include a low quiescent current, typically around 120µA, which makes it ideal for battery-powered applications. The MAX660MX/NOPB's shutdown mode further reduces current consumption to less than 1µA. It also integrates thermal shutdown protection and features over-temperature and short-circuit protection to enhance reliability.
The MAX660MX/NOPB is available in an 8-pin SOIC package, which is compact and suitable for space-constrained applications. Its simplicity, efficiency, and protection features make it a popular choice for portable electronics, sensor networks, and various other low-power applications.
