Product Overview

RT2875B synchronous step-down converter evaluation board. The RT2875B is a high efficiency, current-mode synchronous DC/DC step-down converter that can deliver up to 3A output current over a wide input voltage range from 4.5V to 36V. The device integrates 95mohm high-side and 70mohm low-side MOSFETs to achieve high conversion efficiency. The current-mode control architecture supports fast transient response and simple external compensation. A cycle-by-cycle current limit function provides protection against shorted output and an external soft-start eliminates input current surge during start-up. The RT2875B provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection and thermal shutdown.
  • 3A output current, internal N-MOSFETs
  • Current mode control
  • Adjustable switching frequency from 300KHz to 2.1MHz
  • Adjustable current limit from 1.5A to 6A
  • Adjustable output voltage from 0.6V to 24V
  • High efficiency up to 95%
