TPS50602-SP中文资料抗辐射加固型 (RHA) 3V 至 7V 输入、12A 单路、6A 双同步降压转换器数据手册TI规格书

描述 Description

The TPS50602-SP is a dual TPS50601A-SP die, TID and SEE radiation hardened, 7-V, 12-Asingle output or 6-A dual output synchronous step-down converter, which is optimized for ultrasmall form factor designs. This is achieved integrating highly efficiency high-side and low-sideMOSFETs and excellent thermal performance. Further space savings are achieved through the dualoutput configuration, which reduces the overall solution size if multiple 6-A rails are needed. Theoutput voltage startup ramp is controlled by the SS/TR pin which allows operation as either a standalone power supply or in tracking applications. Power sequencing is also possible by correctlyconfiguring the enable and the open drain power good pins. Thermal shutdown disables the part whendie temperature exceeds thermal shutdown temperature.
