Semtech TS30042Q

High Efficiency 1A/2A Current-Mode Synchronous Buck Converter, 2.2MHz

Add to Watch List

The TS30042Q (2A) is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation and full fault protection. The switching frequency of 2.2 MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs.


  • 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)
  • 2.2MHz ±10% fixed switching frequency
  • Continuous output current: 1A for TS30041Q and 2A for TS30042Q
  • High efficiency up to 90%
  • Current mode PWM control with PFM mode for improved light load efficiency
  • Voltage supervisor for VOUT reporting (Power Good)
  • Input supply under voltage lockout and soft start
  • Full protection for over-current, over-temperature, and VOUT over-voltage
  • SYNC function on EN/SYNC pin to control switching frequency
  • Less than 10uA in standby mode with low external component count
  • AEC-Q100 Grade-2 qualified


  • Power rails in automotive applications
  • Industrial power supplies


  • Packaged in a 16pin QFN (3x3)
