TL3842P,High-Performance Current-Mode PWM Controller,DIP-8

The TL3842P is a high-performance current-mode PWM controller specifically designed for fixed-frequency DC-to-DC and off-line power converter applications. This versatile controller simplifies circuit design with features like automatic feed-forward compensation, pulse-by-pulse current limiting, and a precision error amplifier. Its low start-up current of less than 1mA makes it a cost-effective solution for energy-efficient power supplies.

Engineered for reliability, the TL3842P includes built-in protection mechanisms such as undervoltage lockout with hysteresis and double-pulse suppression to ensure safe and stable operation. Its high-current totem-pole output stage is optimized for driving power MOSFETs, making it a preferred choice for various power management designs.

The TL3842P supports adjustable oscillator frequencies up to 500kHz, allowing flexibility for different design requirements. Packaged in a compact DIP-8 form factor, this controller is an excellent choice for industrial, consumer, and automotive power supply designs.
