The Texas Instruments TPS65283-1RGER is a synchronous dual buck converter designed for power management applications. It operates with an input voltage range of 4.5 V to 18 V, providing flexibility for various power sources.
This converter integrates two buck converters with maximum continuous current capabilities of 3.5 A for Buck1 and 2.5 A for Buck2. The output voltage is adjustable down to 0.6 V with a ±1% feedback reference voltage accuracy. The switching frequency can be adjusted from 200 kHz to 2 MHz, allowing for optimization of performance and component size.
Key features include adjustable current limit, enable functionality, frequency synchronization, light-load efficiency, power good indication, and a fixed soft-start time of 2.4 ms. It also incorporates a power distribution switch with a low on-resistance of 60 mΩ and adjustable current limiting up to 2.7 A.
The TPS65283-1RGER is available in a 24-lead VQFN package measuring 4 mm × 4 mm, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ).
