The Texas Instruments TL3844DR is an economy single-ended, current-mode PWM controller. It is optimized for off-line and DC-to-DC converter applications, requiring a minimal number of external components. This controller features a wide operating voltage range of 10V to 30V and operates at frequencies up to 500kHz.
Key internal circuits include undervoltage lockout (UVLO) with hysteresis, pulse-by-pulse current limiting, and double-pulse suppression. It also has a high-current totem-pole output and an internally trimmed bandgap reference. The TL3844DR is designed to be interchangeable with the UC2842 and UC3842 series.
This component is housed in a 14-SOIC package and is suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C. The maximum duty cycle is 48%.
The TL3844DR is designed for applications such as step-up, step-up/step-down, boost, flyback, and forward converters.
