• FPGA/ASIC point-of-load regulation
• Network routers and switches
• Industrial automation controllers
• Portable medical devices
• 5G infrastructure power systems

About Texas Instruments

Texas Instruments (TI) is a global semiconductor leader with over 90 years of innovation in analog and embedded processing technologies. Their power management ICs set industry benchmarks for efficiency, thermal performance, and reliability across automotive, industrial, and consumer markets.

TI’s rigorous quality control and vertical integration ensure consistent product performance. Their comprehensive technical resources—including reference designs and simulation tools—provide engineers with unmatched design support, making TI regulators the preferred choice for mission-critical applications.

About DC-DC Switching Regulators

Switching regulators efficiently convert higher input voltages to lower regulated outputs with minimal power loss. Unlike linear regulators, they use pulse-width modulation (PWM) and magnetic storage elements to achieve superior thermal performance at high current levels.

Buck converters like the TPS562201 are essential for modern electronics, enabling battery-powered devices to maximize runtime and reducing heat dissipation in densely packed PCBs. Their ability to handle wide input ranges makes them ideal for systems powered by unstable sources like automotive batteries or solar panels.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats for automated assembly. Contact PCX for reel quantities and custom packaging requests.

FAQs

Q: Does this regulator require external compensation?
A: No – the D-CAP2™ control architecture provides inherent stability without external compensation components.

Q: What is the typical efficiency at 2A load?
A: Efficiency exceeds 90% under typical 12V-to-3.3V conversion conditions (see datasheet for curves).

Q: Is this IC suitable for automotive applications?
A: While industrial-grade (-40°C to +125°C), it isn’t AEC-Q100 qualified. For automotive needs, inquire about TI’s TPS54xxx-Q1 series.

Q: Can I parallel multiple TPS562201 regulators?
A: Yes – use phase-spreading techniques to reduce input ripple. Refer to TI app note SLVA369 for implementation.

Q: How does Eco-Mode™ improve light-load efficiency?
A: It automatically reduces switching frequency below 580kHz during light loads, cutting quiescent current to 18µA typical.

Q: What inductor value is recommended?
A: 4.7µH is optimal for most 5V/12V input designs. See Section 8.2 of the datasheet for selection guidelines.
