TPS60205DGS

TPS60205DGS Description

The TPS60205DGS from Texas Instruments is a fixed-output charge pump DC-DC converter designed to deliver a stable 3.3V output from an input voltage range of 1.6V to 3.6V. This compact, surface-mount IC is housed in a 10-VSSOP package and is ideal for low-power applications requiring efficient voltage conversion without inductors. With a switching frequency of 300kHz, it provides a 100mA output current, making it suitable for battery-powered and space-constrained designs. The device operates asynchronously, eliminating the need for external synchronization, and features RoHS3 compliance and REACH unaffected status, ensuring environmental and regulatory compatibility.
