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. …
