TC7662AEPA  

DC Switching Voltage Regulators

TC7662AEPA Description

The TC7662AEPA from Microchip Technology is a charge pump voltage inverter/regulator designed to generate positive or negative fixed outputs from a single input voltage. Housed in an 8-pin DIP package, it operates over a wide input range of 3V to 18V, delivering up to 40mA output current with a switching frequency of 12kHz. This ratiometric, non-synchronous charge pump is ideal for applications requiring compact, efficient voltage inversion or doubling without inductors. Its through-hole mounting ensures robust integration in prototyping or industrial designs, while ROHS3 compliance and REACH unaffected status make it environmentally friendly.

TC7662AEPA Features

• Wide Input Range (3V–18V): Supports diverse power sources, from batteries to regulated supplies.
• Fixed Output Configuration: Generates positive or negative voltages with minimal external components.
• High Efficiency (Charge Pump Topology): Eliminates inductors, reducing board space and cost.
• Low Output Current (40mA): Optimized for low-power systems like sensors or portable devices.
• 12kHz Switching Frequency: Balances noise and efficiency for stable performance.
• Robust Packaging (8DIP): Suitable for through-hole designs with high reliability.
• Ratiometric Operation: Output scales linearly with input, simplifying calibration.
• RoHS3/REACH Compliant: Meets stringent environmental standards.

TC7662AEPA Applications

• Voltage Inversion: Converts positive supplies to negative rails for op-amp circuits, data converters, or biasing applications.
• Portable Electronics: Powers low-current subsystems in handheld devices, medical sensors, or IoT nodes.
• Industrial Controls: Provides isolated or auxiliary voltages in PLC modules and instrumentation.
• Automotive Systems: Suitable for non-critical low-power circuits due to its wide input range.
• Test Equipment: Generates dual supplies for prototyping boards or bench tools.

Conclusion of TC7662AEPA

The TC7662AEPA stands out for its simplicity, versatility, and compact design, making it a go-to solution for low-power voltage conversion. Its inductorless topology reduces design complexity, while the wide input range ensures compatibility across industries. Whether for portable devices, industrial systems, or precision analog circuits, this charge pump delivers reliable performance with minimal external components. A cost-effective choice for engineers seeking efficient, space-saving voltage management.
