TPS564201DDCT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS564201DDCT is a synchronous step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion in compact spaces. It features a wide input voltage range of 4.5 V to 17 V and delivers up to 4 A of output current. The device utilizes D-CAP2 mode control to ensure rapid transient response without requiring external compensation components. Operating at a fixed switching frequency of 560 kHz, it supports adjustable output voltages from 0.76 V to 7 V. Integrated into a SOT-23-THIN-6 package, the regulator includes pulse-skip mode operation for improved light-load efficiency and comprehensive protection mechanisms such as thermal shutdown and overcurrent limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• D-CAP2 mode control enables fast transient response and eliminates the need for external compensation networks.
• Pulse-skip mode operation maintains high efficiency during light-load conditions by reducing switching activity.
• Integrated synchronous rectification with low on-resistance internal FETs minimizes conduction losses.
• Comprehensive protection suite includes thermal shutdown, non-latching undervoltage lockout, and cycle-by-cycle overcurrent limiting.

• Digital television power supplies
• High-definition Blu-ray disc players
• Networked home terminal devices
• Digital set-top boxes (STBs)
• Monitoring equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix 'CT' corresponds to the Cut Tape packaging variant rather than the Reel variant ('CR'). Confirm the specific pinout configuration matches the SOT-23-THIN-6 footprint requirements for the target PCB layout. Ensure the selected component meets the required thermal performance specifications for the intended operating environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for applications demanding up to 4 A output current from a 4.5 V to 17 V input source. It is suitable for designs prioritizing minimal external component count and fast transient response. Consider the thermal dissipation capabilities of the SOT-23-THIN-6 package relative to the expected load current and ambient temperature conditions.
