TPS50602-SP (PREVIEW) Radiation Hardness Assured (RHA) 3-V to 7-V input, 12A single, 6A dual synchronous buck converter

 

Description

The TPS50602-SP is a dual TPS50601A-SP die, TID and SEE radiation hardened, 7-V, 12-A single output or 6-A dual output, synchronous step-down converter, optimized for ultra small form factor designs. This is achieved by integrating high efficiency high-side and low-side MOSFETs and excellent thermal performance. Further space saving is achieved through the dual output configuration, which reduces the overall solution size when multiple 6-A rails are needed. The output voltage start-up ramp is controlled by the SS/TR pin that allows operation as either a stand alone power supply or in tracking applications. Power sequencing is also possible by configuring the enable and the open drain power-good pins. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.
