Product Overview: Texas Instruments TPS60311DGS

The Texas Instruments TPS60311DGS is a high-efficiency, low-noise, dual-output, step-up charge pump that is designed for battery-powered and low-power handheld applications. This device is specifically engineered to provide a stable power supply from a single-cell battery, which typically ranges from 0.9V to 1.8V, to extend the life of the battery and maintain consistent device performance.

The TPS60311DGS operates by doubling the input voltage to provide two regulated output voltages, which can be set to either 3.3V or 5V using the select pin (SEL). This feature makes it an excellent choice for powering devices that require dual voltage levels, such as handheld computers, PDAs, mobile phones, and other portable gadgets.

Key Features:

• Input Voltage Range: 0.9V to 1.8V, suitable for single-cell battery operation.
• Dual Output Voltages: Selectable 3.3V or 5V outputs to accommodate various digital components.
• High Efficiency: Up to 90% efficiency, reducing energy loss and heat generation.
• Low Noise Operation: Integrated low ripple charge pump technology ensures minimal interference with sensitive RF and analog circuits.
• Power-Save Mode: Reduces quiescent current to extend battery life in light load conditions.
• Small Package Size: Available in a compact VSSOP-10 package, ideal for space-constrained applications.

The TPS60311DGS also features a low-power shutdown mode, which significantly reduces the current consumption to a mere 0.1µA, further prolonging the battery life when the device is not in active use. Additionally, the built-in thermal shutdown protection ensures that the device operates within safe temperature limits.

With its advanced circuitry and high level of integration, the TPS60311DGS is designed for seamless integration into various portable applications. It provides designers with a reliable and efficient power management solution that minimizes the need for external components, simplifying the design process and accelerating time to market.
