TPS563200 Synchronous Step-Down Regulator

TI's 17 V input, 3 A, synchronous step-down regulator in a SOT-23 with advanced Eco-mode™

Image of Texas Instruments TPS563200 Synchronous Step-Down RegulatorTexas Instruments' TPS563200 is a simple, easy-to-use, 3 A synchronous step-down (buck) converter in an SOT-23 package. The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current.

This switch mode power supply (SMPS) devices employs D-CAP2 mode control providing a fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.

The TPS563200 operates in Advanced Eco-mode, which maintains high efficiency during light-load operation. The device is available in a 6-pin 1.6 × 2.9 mm SOT (DDC) package, and specified from –40°C to 85°C of ambient temperature.

Features
  • D-CAP2 mode control with 650 kHz switching frequency
  • Input voltage range: 4.5 V to 17 V
  • Output voltage range: 0.76 V to 7 V
  • Integrated 68 mΩ and 39 mΩ FETs
  • Advanced Eco-mode pulse-skip
  
  • Low shutdown current less than 10 µA
  • 1% feedback voltage accuracy (25°C)
  • Startup from pre-biased output voltage
  • Cycle-by-cycle hiccup over-current limit
  • Non-latch OVP, UVLO and TSD protections
