Description
The TPS60403DBVR is a high-efficiency charge pump voltage inverter designed to generate a negative output voltage from a single positive input supply. Operating with a fixed 250kHz frequency, this IC is specifically engineered for space-constrained applications requiring a simple negative rail for op-amps, RS-232 level shifters, or other analog circuitry. By utilizing a charge pump architecture, it avoids the need for bulky inductors, significantly reducing board footprint and electromagnetic interference (EMI).
This device is capable of delivering up to 60mA of output current, making it an excellent choice for a wide variety of portable and low-power electronic designs. Its integrated circuitry ensures stable performance and reliable operation across the specified input range. Housed in a compact SOT-23 (SMD-5) package, the TPS60403DBVR is the ideal solution for generating secondary voltage rails in battery-powered devices, handheld instruments, and compact industrial modules where board space is at a premium.
Key Features
- Voltage Inversion: Efficiently generates a negative voltage rail from a positive input source (e.g., inverting $V_{IN}$ to $-V_{IN}$).
- 60mA Output Capacity: Sufficient current handling for various analog and signal-processing applications.
- Fixed 250kHz Operation: Provides a predictable, stable switching frequency that simplifies external filtering.
- Inductorless Design: Uses external capacitors rather than inductors, resulting in a significantly smaller and quieter power solution.
- Compact SMD-5 Package: Industry-standard SOT-23 footprint optimized for high-density, modern surface-mount PCB layouts.
Application
- Negative Rail Generation: Ideal for powering operational amplifiers, sensors, and data converters that require dual-supply rails.
- RS-232 Level Shifting: A perfect power source for serial communication interfaces requiring negative voltage levels.
- Portable Instrumentation: Efficiently adds a negative rail to battery-operated handheld diagnostic and monitoring equipment.
- Mixed-Signal Systems: Simplifies power management in compact designs needing both positive and negative voltages.
- General Electronics: A versatile building block for engineers looking to generate a low-power negative supply without adding complex inductor-based circuitry.
