MPN:TLC5551P

The TLC555 is a CMOS version of the classic 555 timer IC from Texas Instruments, designed for high accuracy and very low power consumption. Compared to the standard NE555, the TLC555 offers much lower supply current, higher input impedance, and better timing accuracy, making it ideal for battery-powered and portable electronic applications.

It supports monostable, astable, and bistable modes, and works reliably in timers, pulse generators, LED flashers, PWM circuits, and clock generators.

MPN:TYN612M

The TYN612M is a high-performance SCR (Silicon Controlled Rectifier) from STMicroelectronics, designed for reliable control of AC and DC power circuits. With a 12A average on-state current and 600V repetitive peak off-state voltage, it is ideal for motor control, power supplies, heating controllers, and industrial automation applications.

This SCR offers high surge current capability, excellent thermal stability, and rugged construction, making it suitable for demanding power electronics designs.

MPN:UC3843AN

The UC3843AN is a high-performance current-mode PWM controller IC from Texas Instruments, widely used in switch-mode power supplies (SMPS). It offers precise duty-cycle control, fast transient response, and excellent line/load regulation, making it ideal for offline and DC-DC converter designs.

With features like under-voltage lockout (UVLO), low start-up current, and cycle-by-cycle current limiting, the UC3843AN ensures safe, stable, and efficient power conversion.

MPN:UC3843B

The UC3843B is a current-mode PWM controller IC from STMicroelectronics, designed for high-efficiency switch-mode power supplies (SMPS). It provides precise duty-cycle control, fast dynamic response, and excellent line and load regulation, making it ideal for flyback, forward, and DC-DC converter designs.

With built-in features such as under-voltage lockout (UVLO), low start-up current, and cycle-by-cycle current limiting, the UC3843B ensures safe, stable, and reliable power control in both consumer and industrial power systems.
