The TL2843BDR-8 is a high-performance current-mode PWM controller designed for DC-DC conversion applications. It operates with a low start-up current of less than 0.5 mA and features a trimmed oscillator discharge current of 8.3 mA. This controller supports a maximum switching frequency of 500 kHz and includes automatic feed-forward compensation for improved performance. Key features include latching PWM for cycle-by-cycle current limiting, an internally trimmed reference with undervoltage lockout (UVLO), and a high-current totem-pole output stage suitable for driving N-channel MOSFETs. The device is characterized for operation over a temperature range of -40¬8C to 85¬8C, making it suitable for various applications. The TL2843BDR-8 is pin-compatible with standard TL284x series devices, offering enhancements in start-up current and UVLO performance. It is available in an 8-pin SOIC package, making it a compact solution for engineers looking to implement efficient DC-DC conversion in their designs.
