Pulse-Width-Modulation Control Circuits
TL494
Electrical characteristics over recommended operating free-air temperature range,
Vcc=15V, f=10kHz (unless otherwise noted)
Amplifier section (See Figure 2)
*For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
** All typical values except for parameter changes with temperature are at TA =25 oC
*** Duration of the short-circuit should not exceed one second.
**** Standard deviation is a measure of the statistical distribution about the mean as derived from the formula.
***** Temperature coefficient of timing capacitor and timing resistor not taken into account.
