Figure 3. SCP Circuit  
The timer operates by charging an external capacitor (C ), connected between the SCP terminal and ground,  
SCP  
towards 2.5 V through a 185-kresistor (R  
). The circuit begins charging from an initial voltage of approximately  
SCP  
185 mV and times out when the capacitor voltage reaches 1 V. The output of SCP comparator 2 then goes high,

output transistor  
The output of the TL5001/A is an open-collector transistor with a maximum collector current rating of 21 mA and  
a voltage rating of 51 V. The output is turned on under the following conditions: the oscillator triangle wave is lower  
than both the DTC voltage and the error-amplifier output voltage, the UVLO circuit is inactive, and the short-circuit  
protection circuit is inactive.
