The NCV3843BVD1R2G is a high-performance fixed frequency current mode controller designed for Off-Line and DC-DC converter applications. It operates with a trimmed oscillator for precise duty cycle control and features a temperature-compensated reference, high gain error amplifier, and a current sensing comparator. The device supports a maximum oscillator frequency of 250 kHz and can operate in current mode up to 500 kHz. Key protective features include undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and programmable output deadtime. The NCV3843BVD1R2G is available in an 8-pin SOIC package and is suitable for lower voltage applications, with undervoltage lockout thresholds of 8.5 V (on) and 7.6 V (off). It is also Pb-free, making it compliant with environmental regulations. The operating temperature range is from -40°C to +125°C, which enhances its applicability in various environments.
