The TL2844BDR is a current mode PWM controller from Texas Instruments designed for boost and flyback converter topologies. It operates at frequencies up to 500kHz and features a trimmed oscillator discharge current of 8.3mA typical.
This controller offers a low start-up current of less than 0.5mA maximum, making it suitable for power-sensitive applications. The undervoltage lockout (UVLO) thresholds are set at 16V for turn-on and 10V for turn-off, providing reliable power-up and brownout protection.
The device is housed in a 14-pin SOIC package, supporting surface-mount assembly for compact power supply designs. Its current mode architecture provides inherent pulse-by-pulse current limiting and simplified loop compensation.
