3 Pin Description

3.5 OSC Pin (Oscillator Frequency):

An Rt-Ct network must be connected on that to define the switching frequency. Note that

despite the connection of Rt to VDD, no significant frequency change occurs for VDD varying

from 8V to 15V. It provides also a synchronisation capability, when connected to an external

frequency source.
