The Texas Instruments TL2842BDR-8 is a high-performance current-mode PWM controller designed for off-line or DC-to-DC fixed-frequency current-mode control schemes. It features a low start-up current of less than 0.5mA and operates at frequencies up to 500kHz.
This controller supports Boost, Flyback, and Forward topologies, offering positive output configurations for Step-Up and Step-Up/Step-Down applications. It operates with an input voltage range of 10V to 30V and has a maximum duty cycle of 96%. The device is housed in an 8-SOIC package and is suitable for surface mount applications.
Key electrical features include trimmed oscillator discharge current and internally trimmed reference with undervoltage lockout. The output stage is a totem-pole design capable of sourcing or sinking high-peak current, making it ideal for driving N-channel MOSFETs. The operating temperature range is -40°C to 85°C.
Applications include switching regulators of any polarity and transformer-coupled DC/DC converters. The TL2842BDR-8 provides essential features for implementing efficient power control with a minimal number of external components.
