TL2845BDR-8 TI DC DC Switching Controllers
The TL2845BDR-8 is a current-mode PWM controller from Texas Instruments, optimized for off-line and DC-DC converter applications. It operates with a supply voltage range of 7.6V to 30V and features an oscillator frequency of up to 500 kHz. The controller includes a trimmed oscillator for precise frequency control, a high-gain error amplifier, and a 1A peak totem-pole output. Under-voltage lockout (UVLO) has a start-up voltage of 8.4V. Housed in an 8-pin SOIC package, it is characterized for -40°C to 85°C. It is ideal for flyback and forward topology power supplies in telecommunications equipment and industrial systems.
