Toote ülevaade

The TPS54339DDA is an adaptive on-time D-CAP2™ mode synchronous Buck Converter for use with digital set-top box (STB). The TPS54339 enables system designers to complete the suite of various end-equipment power bus regulators with low component count and low standby current solution. The main control loop for the TPS54339 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components. The TPS54339 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP and ultra-low ESR ceramic capacitors. The device operates from 4.5 to 23V VIN input. The output voltage can be programmed between 0.76 and 7V. The device also features an adjustable soft-start time.
  • D-CAP2™ mode enables fast transient response
  • Low output ripple and allows ceramic output capacitor
  • Highly efficient integrated FETs optimized for lower duty cycle applications
  • High initial bandgap reference accuracy
  • Adjustable soft-start
  • pre-biased soft-start
  • Cycle-by-cycle overcurrent limit
  • High efficiency, less than 10µA at shutdown
  • Green product and no Sb/Br
