RTQ2131B, 36V, 1A, Synchronous Step-Down Converter

Overview

TopologyBuck Converter
Input voltage7-25 V
Output 15 V / 1 A

Description

he Evaluation Board demonstrates the RTQ2131B to be designed for a 5V/1.0A output from a 7V to 25V input at 2.1MHz switching frequency. The RTQ2131B 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 RTQ2131B datasheet. The wide input range makes it suitable for automotive systems and car camera module. The RTQ2131B provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection, and thermal shutdown. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.

Typical applications

  • Automotive systems and car camera module
