Datasheet Summary
Powered by GS/AI

The TOP414GN-TL is a three-terminal DC to DC PWM switching regulator designed for high efficiency and versatility in various applications, including telecom and cable communication. It integrates a high voltage N-channel power MOSFET, a voltage mode PWM controller, and fault protection features, which collectively reduce component count and system complexity. The device supports multiple topologies such as Buck, Boost, Flyback, and Forward, and operates effectively with input voltages down to 16 V DC. This regulator achieves over 80% efficiency in Flyback topology, thanks to its low capacitance MOSFET and built-in start-up and current limit functions that minimize DC losses. It features a maximum duty cycle of 70%, which helps reduce conduction losses. The device is packaged in an SMD-8 format, allowing for a compact design under 12 mm in height, and it requires only one external capacitor for compensation and start-up functions. The TOP414GN-TL also includes system-level fault protection with auto-restart and cycle-by-cycle current limiting, as well as on-chip thermal shutdown to safeguard against overload conditions. With an output power capability of up to 21 W, this regulator is suitable for applications requiring reliable and efficient power conversion.
