The TLF51801ELV regulator drives external power stages (n/n-MOS) up to 10A. Output voltage is adjustable with 2% tolerance. Integrated bootstrap diode saves components. Switching frequency ranges from 100 kHz to 700 kHz or syncs to external clock. Soft-start limits inrush current. Enable function enables power management. Includes current limitation, over-temperature shutdown, and undervoltage lockout for protection.

Features

  • Controller for loads up to 10A
  • Driving external power-stage (n/n-MOS)
  • Current limitation using the Rdson
  • Adjustable o/p V: 1.2V up to Dmax*Vs
  • ± 2% output voltage tolerance
  • Duty cycle > 99%
  • Input voltage range from 4.75V to 45V
  • Switching frequency:100 kHz upto 700 kHz
  • Syncronization input
  • EN for ultra-low shut-down current
  • Integrated soft-start function

Benefits

  • Rdson limits, saves shunt & board space.
  • High duty cycle allows low drop-out
