Microchip Technology TC1044SCPA Charge Pump Converter

The TC1044SCPA is a pin-compatible upgrade to the industry-standard TC7660 charge pump, capable of converting a +1.5V to +12V DC input into a corresponding -1.5V to -12V DC output using only two low-cost capacitors. This design eliminates the need for inductors, reducing cost, size, and electromagnetic interference (EMI). The device features an extended supply voltage range up to 12V and includes a frequency boost pin for higher operating frequencies, enabling the use of smaller external capacitors. The onboard oscillator operates at a nominal frequency of 10kHz, which can be increased to 45kHz when the frequency boost pin is connected to the supply voltage. If lower frequency operation is desired for reduced power consumption, an external capacitor can be connected from OSC to ground with the boost pin open. It efficiently converts +5V logic supply to ±5V with a conversion efficiency of approximately 99.9% and power efficiency of 98%. The typical current consumption at 5V is around 80 microamperes. This device is easy to use, requiring only two external capacitors, and is suitable for applications such as power management and RS-232 negative voltage supply. It also offers improved electrostatic discharge (ESD) protection up to 10kV and does not require an external diode for high voltage operation. Please note that this device is sensitive to ESD handling, and delivery times may vary due to market demand.
