The TL2843BP from Texas Instruments is a high-performance current-mode PWM controller designed for efficient off-line or DC-to-DC fixed-frequency control schemes. It operates with a voltage range of 7.6V to 30V and supports switching frequencies up to 500kHz.
Key features include low start-up current (<0.5mA), trimmed oscillator discharge current, and automatic feed-forward compensation. The device incorporates latching PWM for cycle-by-cycle current limiting and an internally trimmed reference with undervoltage lockout. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs.
This controller is available in an 8-PDIP package and is characterized for operation over a temperature range of -40°C to 85°C. Its versatile functionality makes it suitable for various switching regulator applications, including those requiring boost, flyback, or forward topologies.
The TL2843BP offers a maximum duty cycle of 96% and features frequency control. Its through-hole mounting type simplifies integration into existing circuit designs.
