Texas Instruments TPS50601-SP 1.6-V to 6.3-V input, 6-A Synchronous Step Down Swift Converter TPS50601MHKHV

The TPS50601-SP is a radiation-hardened synchronous step-down converter designed for input voltages ranging from 1.6 V to 6.3 V and capable of delivering up to 6 A of output current. It features integrated high-side and low-side MOSFETs with on-resistances of 55 m,Ѷ and 50 m,Ѷ, respectively, which contribute to its high efficiency, peaking at 95% at an output voltage of 3.3 V. The device supports flexible switching frequency options from 100 kHz to 1 MHz, allowing for optimization based on application requirements. This converter is suitable for space satellite applications and other radiation-tolerant environments, with a total ionizing dose (TID) rating of 100 krad (Si) and immunity to single event latchup (SEL) at a linear energy transfer (LET) of 85 MeV-cm¬=/mg. It includes features such as adjustable soft start, power good output, and input undervoltage lockout, enhancing its usability in various power management scenarios. The TPS50601-SP is packaged in a thermally enhanced 20-pin ceramic flatpack, making it suitable for compact designs.
