TPS62363YZHR

The TPS62363YZHR is a high-frequency synchronous step-down (buck) DC-DC converter built to power the core rail of a processor or DSP. It takes a 2.5V to 5.5V input, covering common single-cell battery chemistries, and delivers a programmable 0.5V to 1.77V output in 10mV steps through an I2C-compatible interface, with up to 3A of peak load current. Switching at a typical 2.5 MHz and housed in a 16-bump 2 x 2mm NanoFree package, it targets the tight board area and dynamic-voltage needs of smartphones, tablets, and handheld computers. It is a power-management IC rather than a processor, supplying the rail a processor runs on.

Key Features

• 3A processor core supply - up to 3A peak output current for low-voltage DSP and processor cores, including latest submicron processes.
• I2C voltage scaling - a High-Speed-compatible I2C interface sets the output from 0.5V to 1.77V in 10mV steps for dynamic voltage scaling.
• Fast operating-point transitions - dedicated hardware input pins switch quickly between performance and retention operating points.
• DCS-Control architecture - combined with differential load sensing, it holds precise static and transient output regulation.
• Wide input range - 2.5V to 5.5V operation with a power-save mode that lifts efficiency at light loads during processor retention.
• Protection suite - soft start, programmable slew rate, over-temperature protection, and input undervoltage lockout for robust operation.

Typical Applications

• Dynamic-voltage processors and DSPs - supplying scalable core rails for SmartReflex-compliant and similar power schemes.
• Mobile and handheld devices - cell phones, smartphones, tablets, netbooks, and clamshells where board area is scarce.
• Memory and logic rails - compact, accurate point-of-load supply for low-voltage digital loads.

Unique Advantages

• Tiny solution footprint - the 2 x 2mm package and low external component count fit a total solution under 25 square millimeters.
• Remote sense accuracy - differential sensing at the load corrects for drop across the PCB, keeping the core voltage tight where it matters.
• Retention-mode efficiency - the efficiency peak extends toward low output current, saving power while the processor idles in retention.

Why Choose TPS62363YZHR?

The TPS62363YZHR is the right regulator when a design needs an accurate, I2C-programmable core supply for a processor or DSP in minimal space. Its 3A capability, 0.5V to 1.77V scaling range, DCS-Control regulation, remote sensing, and full protection set make it a dependable power stage for mobile and embedded systems that scale voltage with workload. Fast hardware-pin transitions between performance and retention points let it track a processor's power states in real time, while the 2.5 MHz switching frequency keeps the external inductor and capacitors small.
