The TC1121EPA from Microchip Technology is a versatile charge pump voltage converter. It efficiently converts a 2.4V to 5.5V input voltage to a corresponding negative output voltage, making it suitable for inverter mode applications. This device boasts a high output current capability of 100mA and operates with selectable oscillator frequencies ranging from 10kHz to 200kHz, allowing for the use of small external capacitors and reducing component count as no inductors are required.
The TC1121EPA features a low operating current of 50μA when the frequency control pin is grounded and can be further reduced to less than 1μA in shutdown mode, contributing to power efficiency. It is available in an 8-pin PDIP package, designed for through-hole mounting. The device operates across a wide temperature range of -40°C to 85°C, ensuring reliability in various environmental conditions.
Key applications for the TC1121EPA include laptop computers, medical instruments, disk drives, μP-based controllers, and process instrumentation where a compact and efficient negative voltage generation is needed. Its design simplifies power supply circuitry by eliminating the need for inductors, reducing size, cost, and electromagnetic interference (EMI).
