The TPS61291DRVR is a high-efficiency step-up converter integrated circuit (IC) component manufactured by Texas Instruments. It is designed to provide regulated voltages with input voltages as low as 0.3V, making it suitable for applications in single-cell, dual-cell, or alkaline battery-powered systems. The key features of the TPS61291DRVR include:
1. High Efficiency: The IC provides up to 95% efficiency by employing a synchronous rectifier and adaptive constant frequency pulse width modulation (PWM) control. This ensures minimal power loss and extends the battery life in portable devices.
2. Wide Input Voltage Range: The TPS61291DRVR has a wide input voltage range, from as low as 0.3V up to 5.5V, enabling it to operate with various power sources such as single- or dual-cell batteries, supercapacitors, or energy harvesting devices.
3. Output Voltage Range: It supports an output voltage range from 1.8V to 5.25V, ensuring compatibility with a wide range of applications and devices.
4. Adjustable Switching Frequency: The switching frequency can be programmed between 1.5 MHz and 2.5 MHz using an external resistor. This allows designers to optimize efficiency and external component size based on their specific requirements
