  DESIGN IDEAS Boost DC/DC Converter Synchronizes
  to any Frequency
  by Gary Shockey
  Power supplies that employ switching regulators often require tight
  control over the oscillator switching
  frequency, mainly in an effort to control high frequency noise that can
  interfere with sensitive circuitry. The
  LT1310 switching regulator can be
  synchronized to an external frequency, thus containing noise to
  well-defined frequency bands, which
  can be easily filtered.
  The LT1310 combines a 1.5A Boost
  PWM DC/DC converter with an integrated phase-locked loop, which can
  be synchronized to any frequency
  between 10kHz and 4.5MHz. Figure 1
  shows an application that converts
  5V to 12V with an externally controlled switching frequency of 1.6MHz.
  To synchronize to an external input
  signal, the timing capacitor and PLL
  filter components must be chosen
  properly. This is a simple process and
  can be done using the graph in
  FigureвђЈ 2. …
