The Texas Instruments TPS54386TPWPRQ1 is an automotive-qualified DC/DC switching regulator featuring a dual, non-synchronous buck topology. It operates with an input voltage range of 4.5V to 28V and can deliver up to 3A of output current per channel. The output voltage is adjustable, with a minimum of 0.8V and a maximum of 25.2V.
This device operates at a fixed switching frequency of 600kHz, contributing to efficient power conversion. Key features include an integrated high-side MOSFET with a low on-resistance of 85mΩ, a 0.8V 1.5% voltage reference, and internal compensation for simplified design. It also incorporates pulse-by-pulse overcurrent protection and thermal shutdown protection at 148°C.
The TPS54386TPWPRQ1 is supplied in a 14-pin PowerPAD HTSSOP package, suitable for surface mounting. Its design is optimized for automotive applications, indicated by its AEC-Q100 qualification, with specific results for Device Temperature Grade 2 (-40°C to +105°C Ambient Operating Temperature), HBM ESD Classification Level H2, and CDM ESD Classification Level C3B.
Additional features include dual PWM outputs operating 180° out-of-phase for reduced input/output ripple, selectable overcurrent protection levels for Output 2, and selectable ratiometric or sequential startup modes. The internal soft-start time is 2.1ms.
