Description
Bridgold 20pcs TL494CN TL494 Counter IC,PWM Controller Integrated 20 Piece . Integrated all pulse width modulation circuits. Built-in power transistor provides 500mA drive capability. Bridgold 20pcs TL494CN TL494 Counter IC,PWM Controller Integrated 20 Piece Product Details Built-in linear sawtooth oscillator with only two external oscillating components (resistance and capacitance) Built-in 5V reference voltage source Built-in power transistor provides 500mA drive capability Built-in error amplifier Integrated all pulse width modulation circuits The TL494CN is a PWM Control Circuit incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application.The error amplifiers exhibit a common-mode voltage range. The dead-time control comparator has a fixed offset that provides approximately 5% dead time.The on-chip oscillator can be bypassed by terminating RT to the reference output and providing a saw tooth input to CT or it can drive the common circuits in synchronous multiple-rail power supplies.Minimum Operating Supply Voltage:7 VMaximum Operating Supply Voltage:40 VMinimum Operating Temperature:0 °CMaximum Operating Temperature:+70 °COutput Current:200 (Max) mADimensions:19.3 x 6.35 x 4.57mmMaximum Switching Frequency:300 kHzPackage include:20pcs*TL494CN
