TPS63060DSCR – Buck-Boost Switching Regulator IC 2A WFDFN-10
The TPS63060DSCR from Texas Instruments is a high-efficiency buck-boost switching regulator IC capable of maintaining a stable output voltage for battery-powered systems, regardless of whether the input voltage is above or below the output. Designed for maximum flexibility, it supports input voltages from 2.5V to 12V and provides a regulated output voltage between 2.5V and 8V, with output currents up to 2A. This makes it ideal for products powered by three to six-cell NiMH/NiCd or single/dual-cell Li-Ion/Li-Polymer batteries, ensuring uninterrupted power delivery as the battery discharges.
Built around a fixed-frequency PWM controller with synchronous rectification, the TPS63060DSCR delivers up to 93% efficiency and automatically transitions between buck and boost modes for optimal performance. Its power save mode enhances efficiency at light loads, while the forced fixed-frequency operation (2.4 MHz) enables low-noise operation and easy EMI filtering. The device also includes Buck-Boost Overlap Control ensuring smooth mode transitions and stable output during load or input voltage changes. For safety, it integrates overtemperature protection, overvoltage protection, and load disconnect during shutdown to minimize battery drain.
