Product Overview

The RT7247BHGSP is a high-efficiency monolithic synchronous step-down DC-to-DC Converter can deliver up to 2A output current from a 4.5 to 18V input supply. The RT7247B's current-mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT7247B also provides undervoltage protection and thermal shutdown protection. The low current (<3µA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems.
  • Integrated N-MOSFET switches
  • Current-mode control
  • Stable with low ESR ceramic output capacitors
  • Programmable soft-start
  • Cycle-by-cycle overcurrent limit
  • Undervoltage lockout input
  • Undervoltage protection output
  • Thermal shutdown protection
  • Up to 95% efficiency
  • ±1.5% High accuracy reference voltage
