TPS60311DGSR Voltage Converter by Texas Instruments The TPS60311DGSR, manufactured by Texas Instruments, is a high-efficiency, low-ripple voltage doubler, which is part of the TPS603xx family of charge pump-based voltage converters. This device is designed to provide a regulated output voltage from an unregulated input voltage, making it ideal for battery-powered applications where extended battery life is crucial.

The TPS60311DGSR operates over a wide input voltage range of 0.9V to 1.8V, allowing it to be directly powered by a single-cell NiCd, NiMH, or alkaline battery. It can also be powered by one-cell Li-Ion or Li-polymer batteries, making it highly versatile for various portable devices. The output voltage is fixed at 3.3V with an impressive output current capability of up to 20 mA, which is sufficient for many low-power applications.

This device uses a switched capacitor voltage conversion technique, which results in high efficiency over a wide range of load currents. Its power-saving Pulse Frequency Modulation (PFM) operation at light loads contributes to its low quiescent current and extends battery life in portable systems. Additionally, the TPS60311DGSR features a low-noise regulated output that maintains low ripple voltage, which is essential for sensitive RF and analog circuits.

The TPS60311DGSR is available in a compact MSOP-10 (DGSR) package, which is suitable for space-constrained applications. It also includes over-temperature protection and is specified for the –40°C to 85°C temperature range, ensuring reliable performance across various environmental conditions.

Key applications for the TPS60311DGSR include handheld devices, medical equipment, and any portable electronics requiring a stable power supply with minimal battery drain. With Texas Instruments' reputation for quality and reliability, the TPS60311DGSR is a dependable choice for designers looking to enhance the power efficiency of their products.
