2843B,High-Performance Current-Mode PWM Controller,SOIC-8

The 2843B-SMD (TL2843B) is a high-performance, current-mode pulse-width modulation (PWM) controller designed for off-line and DC-DC converter applications. It features a wide supply voltage range, high switching frequency support, and robust integrated protections. The precision-trimmed reference voltage ensures stability, while the undervoltage lockout and cycle-by-cycle current limiting enhance safety and reliability.

The compact SOIC-8 package makes it suitable for modern designs where space is at a premium. Typical applications include power adapters, industrial power supplies, and battery management systems.

• Current-Mode PWM Controller: Ensures high stability and efficiency for DC-DC and off-line applications.
• Wide Supply Voltage Range: Operates effectively from 4.5V to 30V.
• High Switching Frequency: Supports up to 500 kHz for compact and high-performance designs.
• Integrated Protection: Features undervoltage lockout, current limiting, and thermal shutdown.
• Precision Reference Voltage: 5V reference output with low drift and high accuracy.
• Compact SOIC-8 Package: Ideal for surface-mount and space-constrained designs.
