The TDA38840 OptiMOS™ IPOL 40 A is an easy-to-use, fully integrated DC-DC buck regulator with patented fast Constant-On-Time (COT) control scheme. It simplifies the design effort, while enabling an enhanced transient response and improved Vout regulation. The onboard PWM controller and OptiMOS™ 5 MOSFETs with integrated bootstrap diode make the TDA38840 a small footprint, high efficiency solution for various point-of-load applications.

Features

  • Wide input voltage range from 2-17 V
  • Precision Reference (0.6V +/
  • 0.5%)
  • Compensation free enhanced COT engine
  • forced continuous or diode emulation
  • Switching frequency from 0.6-2MHz
  • Selectable soft-start time
  • Enhanced pre-bias start-up
  • Selectable OCP limit
  • Enable input with voltage monitoring
  • Power Good output
  • Thermal shut down
  • Operating Tj: -40 °C to 125 °C

Benefits

  • Easy to use fast constant on-time
  • High efficiency
  • Accurate output voltage regulation
  • Superior transient response
  • Low BOM
