The TPS65279DAPR from Texas Instruments is a highly integrated dual synchronous buck converter designed for a wide input voltage range of 4.5V to 18V. This device is suitable for various power bus voltages derived from 5V, 9V, 12V, or 15V power supplies and batteries.
Each buck channel in the TPS65279DAPR can deliver up to 5A of continuous output current. For applications requiring higher current, the two buck channels can be paralleled to provide up to 10A of load current using the integrated current sharing feature. The converter utilizes constant frequency peak current-mode control, simplifying compensation and providing fast transient response.
Key features include an adjustable switching frequency from 200 kHz to 1.6 MHz, programmable slew rate control for output voltage transitions, and dedicated enable and soft-start pins for each buck. It also incorporates cycle-by-cycle overcurrent protection and over-temperature protection for enhanced reliability. The device supports Pulse Skipping Mode for improved efficiency at light loads.
The TPS65279DAPR is available in a 32-pin thermally enhanced HTSSOP (DAP) package, suitable for surface mounting. Its design is optimized for applications such as DTVs, telecom and network equipment, point-of-load power supplies, and tablet PCs.
