Beschreibung

The Evaluation Board demonstrates the RTQ6340GQW to be designed for a 5V/0.5A output from a 8V to 42V input at 500kHz switching frequency. The wide input range makes it suitable for communications and industrial 12V, 24V and 36V power systems. The RTQ6340GQW provides complete protection functions such as input undervoltage lockout, output undervoltage protection, overcurrent protection and thermal shut down. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.
