Frequently Asked Questions
What is the input voltage range of the TPS51396ARJET?
The TPS51396ARJET operates with an input voltage range of 4.5 V minimum to 24 V maximum, with a nominal input of 12 V. This wide range accommodates standard 12 V power rails as well as lower-voltage bus applications found in telecommunications and industrial equipment.
What is the maximum output current the TPS51396ARJET can supply?
The TPS51396ARJET supports up to 8 A continuous output current, enabled by its synchronous step-down topology. This makes it capable of powering high-current digital loads such as FPGAs, ASICs, and multi-core processors without requiring external parallel stages.
What control method does the TPS51396ARJET use?
The TPS51396ARJET employs voltage-mode pulse width modulation (PWM) control, providing stable regulation with predictable loop behavior. Voltage-mode control simplifies compensation design and offers excellent noise rejection, making it well suited for mixed-signal and RF-sensitive applications.
What package does the TPS51396ARJET use and what are its thermal benefits?
The TPS51396ARJET is housed in a 20-pin VQFN-HR (S-XQCC-N20) package with an exposed thermal pad on the underside. This exposed pad allows direct heat transfer to the PCB ground plane, significantly reducing junction-to-board thermal resistance for reliable operation up to 125 °C.
Is the TPS51396ARJET RoHS compliant?
Yes, the TPS51396ARJET carries JESD-609 code e3, confirming it is a lead-free, RoHS-compliant component. It is suitable for use in products sold in markets with strict environmental regulations, including the European Union and other regions adopting RoHS standards.
