OSCILLATOR
The chip uses two precision current mirrors that alternately charge and discharge an external capacitor to generate an
extremely linear sawtooth oscillator waveform. At the start of each cycle, the charging current, set by the choice of
resistor at the Rset pin, is 1:1 mirrored over to the Cset pin where it charges an external capacitor. When the capacitor
voltage reaches the comparator’s upper threshold (nominally VREF), the comparator switches current mirrors and begins
to discharge the external capacitor. The discharge current is set at roughly five times the charging current to result in fast
discharge and minimal Dead Time. When the voltage reaches the comparator’s lower threshold (0.9V), the comparator
switches back to the charging mirror, powers down the discharge mirror, and the whole process repeats.
The frequency is set by choosing Rset and Cset such that:
Suggested Ranges for Cset and Rset are:
50K ohms < Rset < 300K
10pf < Cset < 600pF
