Description

The PMP9725 reference design generates a 3.3V output from a 12V input, using the TPS562209 synchronous buck converter.  This converter uses the DCAP2 control method to minimize output capacitance while eliminating feedback compensation components and still providing an excellent load transient response.  The converter switches at 650kHz.  The peak efficiency of this design is 90%.

Features
  • Utilizes DCAP2 control method
  • 90% peak efficiency
  • Small 15mm x 8mm footprint
  • Low profile < 3mm
  • Test report available
