Product Overview: TPS61031PWP by Texas Instruments

The TPS61031PWP is a high-frequency, high-efficiency DC-DC boost converter designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This versatile integrated circuit (IC) is specifically engineered to meet the power management needs of a wide range of applications, including battery-powered devices, portable media players, and other handheld equipment.

Key Features

• Adjustable Output Voltage: The TPS61031PWP allows users to set the output voltage from 1.8V to 5.5V using external resistors, providing flexibility for powering various devices.
• High Efficiency: With a typical efficiency of up to 96%, this converter minimizes energy loss, thus extending battery life in portable applications.
• Switching Frequency: The device operates at a 1.2MHz fixed switching frequency, which enables the use of small, low-cost inductors and capacitors, reducing the overall solution size.
• Low Quiescent Current: The low quiescent current of 35µA (typical) during light loads contributes to further power conservation.
• Power Save Mode: For improved efficiency at light loads, the TPS61031PWP includes a power save mode that reduces the switching frequency to minimize quiescent current.

Protection Features

• Thermal Shutdown: To ensure the device operates within safe temperature ranges, the TPS61031PWP integrates thermal shutdown protection.
• Overvoltage Protection: The built-in overvoltage protection circuit prevents damage to the converter and the load in case of an output voltage surge.
• Under-Voltage Lockout (UVLO): UVLO ensures that the device only operates when the input voltage is within an acceptable range.

Package and Availability

The TPS61031PWP is available in a 20-pin HTSSOP (PWP) package, offering a compact footprint suitable for space-constrained applications. Its robust design and comprehensive set of features make it an ideal choice for designers looking to implement a reliable power management solution.
