Description
The "SEOA713" in the part number might refer to specific package types, temperature ratings, or other identifying attributes unique to that variant. These converters require minimal external components, typically just a few capacitors, and offer features like low operating current and a wide input voltage range.
Overall, the TC7660SEOA713 is ideal for applications needing efficient voltage inversion with minimal power consumption and component count, such as powering negative voltage rail components like operational amplifiers in portable devices. It is favored for its simplicity, reliability, and cost-effectiveness in electronic design.
Equivalent
1. ICL7660S series from Intersil or Renesas.
2. MAX1044 from Maxim Integrated.
3. LTC1044 from Linear Technology (now part of Analog Devices).
4. LM2660 from Texas Instruments.
These components perform similar functions, mainly converting voltages via charge pump techniques, but always check datasheets for pin compatibility and electrical specifications.
Features
Key features include:
- Operating voltage range: 1.5V to 10V
- Output current capability: up to 20mA
- Low quiescent current: typically 80µA
- High efficiency: close to 99% at low loads
- Compact size with an 8-pin SOIC package
- Minimal external components required (two capacitors)
- Wide temperature range: -40°C to +85°C
It is suitable for applications such as generating negative supply voltages for analog circuits, data acquisition systems, and other systems requiring a bipolar power supply from a single positive supply.
Pinout
Here is a concise description of its pin functions:
1. Pin 1 (CAP+): Positive terminal for the charge pump capacitor.
2. Pin 2 (GND): Ground connection.
3. Pin 3 (CAP-): Negative terminal for the charge pump capacitor.
4. Pin 4 (VOUT): Output voltage, which is the inverted (or doubled) version of the input voltage.
5. Pin 5 (LV): Low-voltage operation pin; connects to GND for low-voltage operation.
6. Pin 6 (OSC): Oscillator control or frequency adjustment. Can be connected to an external capacitor to set the oscillation frequency.
7. Pin 7 (VIN): Input voltage, typically a positive supply voltage.
8. Pin 8 (NC): No connection.
The TC7660SEOA713 is typically used for applications requiring a negative voltage rail, such as op-amp power supplies.
Manufacturer
Application
1. LCD Biasing: Provides the necessary negative voltage for driving liquid crystal displays.
