Product Overview

The TPS54340DDA is an adjustable output step down DC to DC converter with Eco-mode in 8 pin SO PowerPAD package. This step down regulator integrates a 92mohm high side MOSFET. The device survives load dump pulses up to 45V per ISO 7637. Current mode contro...
  • Input voltage range from 4.5V to 42V (45V absolute maximum)
  • Adjustable output voltage range from 0.8V to 41.1V
  • 3.5A continuous current and 4.5A minimum peak inductor current limit
  • High efficiency at light loads with pulse skipping Eco-mode
  • Low dropout at light loads with integrated BOOT recharge FET
  • 100KHz to 2.5MHz fixed switching frequency
  • Synchronizes to external clock
  • Adjustable UVLO voltage and hysteresis
  • Internal soft start and accurate cycle by cycle current limit
  • Operating temperature range from -40°C to 125°C
This device has limited built-in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
