TC1240AECHTR MICROCHIP DC DC Switching Regulators

The TC1240AECHTR from Microchip is a CMOS charge pump voltage converter in a compact 6-pin SOT-23A package that doubles an input voltage ranging from 2.5V to 5.5V. For selection, it provides a fixed ratiometric output (2Vin) with a 125kHz internal oscillator frequency, delivering up to 40mA output current from a very low 550µA supply current. The device operates across −40°C to +85°C. In application, it is purpose-built for battery-powered portable devices where a higher voltage rail is needed from a single Li-Ion cell or two-cell alkaline supply. It excels in handheld instruments, PDAs, portable data loggers, and IoT sensor nodes. It also suits power management circuits in consumer electronics, sensing and instrumentation equipment, and any space-constrained design requiring a compact, high-efficiency voltage doubling solution with minimal external components.
