TL494CN TL494C in a DIP16 package, supplied as a 10piece lot, is a pulse width modulation (PWM) control circuit designed for switching power supplies and DCDC converters. It combines core control functions in a compact IC to simplify regulator designs and improve performance. Key benefits Integrated PWM control: provides a complete PWM regulation solution with a built in 5V reference, dual error amplifiers, oscillator, deadtime control, and output transistors. Accurate output regulation: uses feedback from external circuitry through the error amplifiers to maintain stable output voltages under varying load and line conditions. Flexible output configuration: supports drive modes that can be configured for pushpull or parallel operation to suit different transformer or switching topologies. Reduced component count: lowers external part count and board area by including essential control elements in a single DIP16 package. Broad compatibility: widely used in SMPS designs and hobbyist/prototyping projects due to standard DIP16 form factor and established pinout. Key attributes Functionality: PWM control circuit with builtin 5V reference, two error amplifiers, adjustable oscillator, deadtime control input, and two output transistors. Compatibility: DIP16 package (plastic throughhole), commonly used in switchmode power supply designs; compatible with standard SMPS topologies. Size and packaging: 16pin dualinline package (DIP16) suitable for throughhole mounting on PCBs. Material: plastic DIP packaging typical for integrated circuits of this type. Performance characteristics: designed for PWM regulation in power supplies, with a supply voltage range suitable for typical TL494 applications (7V to 40V in many designs) and features enabling stable regulation and control of switching devices via external circuitry. Specifications you typically rely on in designs Builtin 5V reference for accurate sensing and comparison. Two error amplifiers for flexible feedback and control loops. Oscillator with externally connected RT and CT components to determine switching frequency. Deadtime control input to prevent simultaneous conduction of output transistors and to tailor duty cycle. Output stage suitable for driving power switching devices through appropriate external stages (transistors or MOSFETs) as part of a regulator topology. DIP16 form factor for easy integration into standard PCB layouts. Typical applications Offline and ACDC switchmode power supplies: regulate output rails by comparing feedback with the internal reference and adjusting PWM accordingly. DCDC converter regulation: provide stable control signals for buck, boost, or flyback converters in consumer electronics. Prototyping and education: teach PWM regulation concepts, control loop design, and power electronics using a readymade TL494based controller. Usage scenarios A small wallwart or desktop adaptor where the TL494CN controls the primaryside switch via feedback and optocoupler isolation. A compact PC or display power supply where a TL494CNbased controller manages multiple rails with a single PWM domain. A lab project or breadboard experiment to learn PWM regulation with adjustable frequency and duty cycle using external RT/CT components.
