EN/SYNC Function
SLUS602B – JUNE 2004 – REVISED SEPTEMBER 2005
The clock frequency is programmed by the value of the timing resistor connected from the RT pin to ground.
fPH is a single phase frequency, kHz. The RT resistor value is expressed in k. See Figure 4.
Figure 4. Phase Switching Frequency vs. Timing Resistance
The output ripple frequency is twice that of the single phase frequency. The switching frequency of the controller
can be synchronized to an external clock applied to the EN/SYNC pin. The external clock synchronizes the
rising edge of HDRV and the falling edge of an external clock source. The external clock pulses must be at a
frequency at least 8.2 times higher than the switching frequency set by the RT resistor.
