SL494CN, a New AC-DC Controller and Regulator from SLKOR Operated Stably at Switch Frequencies Ranging from kHz to 300kHz
SL494CN is an AC-DC controller and regulator product from SLKOR, which boasts excellent performance and multiple features. As a control circuit of a PWM switch regulator, SL494CN is composed of several key components, including a 5V reference voltage circuit, two error amplifiers, a flip-flop, an output control circuit, a PWM comparator, a dead-time comparator, and an oscillator. The collaboration of these components enables SL494CN to operate stably at switch frequencies ranging from kHz to 300kHz, making it suitable for various application scenarios.
SL494CN has several features, including an internal regulator that provides a stable 5V reference voltage (adjustable to 5%), an uncommitted output for a 200mA sinking or sourcing current, push-pull or single-ended operation for output control, a complete PWM control circuit capable of variable duty cycle, and an on-chip oscillator for master or slave operations. Additionally, the internal circuitry of SL494CN prevents double pulsing at any output, ensuring stability and reliability during operation.
The parameter specifications of SL494CN are as follows: the operating voltage VC is 40V, the output current Io is 250mA, the operating temperature range TSTG is -50 to 150°C, and the package form is SOP-16. These parameter specifications make SL494CN suitable for various environments and operating conditions, and it exhibits high stability and reliability.
Overall, as an AC-DC controller and regulator product, SL494CN has broad application prospects. Its stable and reliable performance characteristics make it widely applicable in industrial control, power management, and other fields. It provides stable and reliable control and drive support for systems, bringing great convenience and value to users. Looking forward to the future development of SL494CN, expecting it to bring greater innovation and breakthroughs to a wider range of applications. In addition to SL494CN, Sark Micro's AC-DC controllers and regulators also include other excellent products, such as SL0610G, SL494CN, SL1007G, and so on.
