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.


  • 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
