Description

The 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.

Characteristics

  • Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 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% fixed switching frequency Continuous output current: 1A (TS30041), 2A (TS30042) High efficiency up to 95% Current mode PWM control with PFM mode for improved light load efficiency Voltage supervisor for VOUT reported at the PG pin Input supply under voltage lockout Soft start for controlled startup with no overshoot Full protection for over-current, over-temperature, and UT over-voltage SYNC function on EN/SYNC pin to control switching frequency Less than 10uA in standby mode Low external component count
