Description

he TS30041 (1A) and TS30042 (2A) are DC/DC synchronousswitching regulators with fully integrated power switches,internal compensation, and full fault protection. The switchingfrequency of 1MHz enables the use of small ! lter componentsresulting in minimal board space and reduced BOM costs.

Features

Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5Vwith +/- 2% output tolerance

  • Adjustable version output voltage range: 0.9V to (VCC -1V) with +/- 1.5% reference
  • Wide input voltage range: 4.5V to 40V (42V Abs Max)
  • 1MHz +/- 10% ! xed switching frequency
  • Continuous output current: 1A (TS30041), 2A (TS30042)
  • High e" ciency up to 95%
  • Current mode PWM control with PFM mode for improvedlight load e" ciency
  • Voltage supervisor for VOUT reported at the Power Good(PG) pin
  • Input supply under voltage lockout
  • Soft start for controlled startup with no overshoot
  • Full protection for over-current, over-temperature, andVOUT over-voltage
  • SYNC function on EN/SYNC pin to control switching frequency
  • Less than 10uA in standby mode
  • Low external component count

Typical applications

  • Industrial power supplies
  • Set-top box, DVD, LCD, LED supply
  • On-card switching regulators
