Bridgold 20pcs TL494CN TL494 Counter IC,PWM Controller Integrated Circuit,300 kHz 16-Pin
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 V Maximum Operating Supply Voltage:40 V Minimum Operating Temperature:0 °C Maximum Operating Temperature:+70 °C Output Current:200 (Max) mA Dimensions:19.3 x 6.35 x 4.57mm Maximum Switching Frequency:300 kHz Package include: 20pcsTL494CN
