The TC7662AMJA from Microchip Technology is a versatile charge pump voltage converter designed for efficient DC-to-DC conversion. It accepts a wide input voltage range from 3V to 18V and generates a negative output voltage ranging from -3V to -18V. This device is pin-compatible with industry-standard parts like the ICL7662 and TC7660, offering an upgrade path with increased output current capability of up to 40mA.
Utilizing CMOS construction, the TC7662AMJA eliminates the need for external diodes and inductors, simplifying circuit design and reducing component count, size, and EMI. The integrated oscillator operates at a nominal frequency of 12kHz, with options for lower frequencies by adding an external capacitor. Its low output impedance, typically 40 Ohms at 20mA load, ensures efficient power delivery.
This charge pump converter is suitable for applications requiring negative voltage generation, such as in laptop computers, disk drives, process instrumentation, and micro-processor-based controllers. It is available in 8-pin PDIP and 8-pin CERDIP packages, supporting a wide operating temperature range from -55°C to +125°C.
Input voltage range is 3V to 18V, output voltage range is -3V to -18V.
