Microchip Technology TC7660SEOA713 Charge Pump DC-DC Converter

The TC7660SEOA713 is a high-performance, versatile charge pump voltage converter manufactured by Microchip Technology. This device is specifically designed to convert a +1.5V to +10V input voltage into a corresponding -1.5V to -10V output voltage, making it an ideal component for applications that require a negative supply voltage from a positive input. This converter is particularly useful for battery-powered and low-power electronics where efficiency and space are critical concerns.

Constructed with CMOS technology, the TC7660SEOA713 offers a range of features that enhance its performance and usability. The device boasts a high power efficiency, which is essential for prolonging battery life in portable devices. Additionally, it has a low quiescent current, further contributing to its energy-saving capabilities.

One of the key advantages of the TC7660SEOA713 is its ease of use. It requires only two external non-critical capacitors for voltage conversion, simplifying the design and minimizing the PCB footprint. Furthermore, it can deliver a guaranteed output current of 20mA, which is sufficient for a wide array of low-power applications.

The converter operates at a high oscillator frequency of 10kHz, which allows for the use of small capacitors while still maintaining low output ripple and noise. This feature is particularly beneficial in applications where clean and stable voltage is necessary, such as in analog circuits and operational amplifier setups.

Another notable feature of the TC7660SEOA713 is its no-load operation, which ensures that the output voltage remains stable even when there is no load present. This characteristic is essential for maintaining the integrity of the power supply in dynamic load conditions.

Overall, the TC7660SEOA713 from Microchip Technology is a reliable and efficient solution for generating a negative voltage rail in space-constrained and power-sensitive applications. Its robust design, combined with its high efficiency and simple external circuitry, make it a go-to choice for designers looking to implement a negative supply voltage in their systems.
