Microchip Technology's TC7660SEPA Charge Pump Voltage Converter

Introducing the TC7660SEPA, a high-performance, versatile charge pump voltage converter from Microchip Technology. Designed to meet the needs of a wide array of applications, this integrated circuit is ideal for portable devices, where extending battery life is crucial. Its ability to convert a positive voltage to the corresponding negative voltage with a high efficiency makes it a perfect choice for small, energy-sensitive systems.

The TC7660SEPA operates over a range of input voltages from +1.5V to +10V, providing a stable output voltage with a minimum of external components. This makes the device not only powerful but also easy to integrate into your existing designs. It delivers a guaranteed output current of 20mA, which is ample for powering low-power operational amplifiers, memory devices, and other analog ICs.

One of the standout features of the TC7660SEPA is its low power consumption. With a typical quiescent current of only 70µA, it ensures that the battery life of your portable device is maximized. Additionally, the no-load supply current is typically a mere 10µA, further enhancing the power efficiency when the device is in standby mode.

The TC7660SEPA also boasts a high frequency operation of up to 70kHz, which allows the use of small, low-cost capacitors with lower capacitance values. This not only saves space on your PCB but also reduces the overall cost of materials for your project.

For designers concerned about reliability, the TC7660SEPA offers thermal shutdown and current limiting features to protect your application from damage. The device is available in an 8-pin PDIP package, ensuring compatibility with standard breadboards and sockets for easy prototyping and testing.

Whether you're designing a battery-operated device, a portable instrument, or any application requiring an efficient voltage inversion solution, the TC7660SEPA from Microchip Technology stands out as a robust, efficient, and cost-effective choice.
