TL2844DR TI PWM Controller | 14-SOIC | 8.3V-30V, 1A Peak Gate Drive

Product Overview

The TL2844DR from Texas Instruments is a high-performance current-mode PWM controller designed for off-line and DC-to-DC converter applications. It features a wide input voltage range, low startup current, and a high-current totem-pole output stage optimized for driving power MOSFETs. The device operates at a fixed frequency of up to 500 kHz and includes essential protection features such as undervoltage lockout (UVLO) and pulse-by-pulse current limiting. Housed in a compact 14-SOIC package, the TL2844DR is ideal for space-constrained power supply designs.
