5 / 19 page OUTPUT TRANSISTOR TL5001A-Q1 www.ti.com .............................................................................................................................................. SLVS603B – AUGUST 2005 – REVISED FEBRUARY 2009 The timer operates by charging an external capacitor (CSCP) connected between the SCP terminal and ground, towards 2.5 V through a 185-k Ω resistor (RSCP). The circuit begins charging from an initial voltage of approximately 185 mV and times out when the capacitor voltage reaches 1 V. The output of SCP comparator 2 then goes high, turns on Q2, and latches the timer circuit. The expression for setting the SCP time period is derived from Equation 3: VSCP = (2.5 – 0.185) (1 – e –t/ τ) + 0.185 (3) Where τ = R SCPCSCP The end of the time-out period (tSCP) occurs when VSCP = 1 V. Solving for CSCP yields Equation 4: CSCP = 12.46 × tSCP (4) Where t is in seconds, C is in µF tSCP must be much longer (generally 10 to 15 times) than the converter start-up period, or the converter will not start. The output of the TL5001A 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.
