Richtek RTQ2130B | Demoboard EVB_RTQ2130BGQW-QT

Description

The Evaluation Board demonstrates the RTQ2130B to be designed for a 5V/0.7A output from a 7V to 25V input at 2.1MHz switching frequency. The RTQ2130B can apply to other output voltages by changing the resistive divider for input voltages support up to 36V. For more application circuits, please refer to the RTQ2130B datasheet. The wide input range makes it suitable for automotive systems and car camera module. The RTQ2130B provides complete protection functions such as input under voltage lockout, output undervoltage protection, overcurrent protection, and thermal shutdown. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.
