TPS60212DGSR

The Texas Instruments TPS60212DGSR is a DC/DC switching regulator utilizing a charge pump topology to provide a regulated 3.3V output voltage. It is designed for battery-powered applications, offering ultra-low operating current in snooze mode (typical 2 uA) and low quiescent current (35 uA), extending battery life. The device can deliver up to 50mA of output current with less than 5mV (PP) output voltage ripple.

Key electrical characteristics include an input voltage range from 1.8V to 3.6V and a switching frequency of 300kHz. It features an integrated low-battery and power-good detector, and its switching frequency can be synchronized to an external clock signal. The TPS60212DGSR boasts up to 90% efficiency, making it a power-efficient solution.

This component is housed in a compact 10-pin VSSOP package, suitable for surface mounting. Its design requires only four external capacitors, simplifying the implementation and reducing board space. The easy-to-design, low-cost, and low EMI nature of this charge pump converter makes it an attractive alternative to traditional DC/DC converters that require inductors.

Applications include replacing inductors in battery-powered devices such as those using two battery cells. The TPS60212DGSR is designed for environments with operating temperatures ranging from -40°C to 125°C (TJ).
