Product Overview

The RT7298AHGQW is a 6A, 18V synchronous step-down converter in 14 pin WQFN package. The RT7298A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 6A output current from a 4.5V to 18V input supply. The RT7298A current-mode architecture with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault condition protections include output under-voltage protection, output over-voltage protection and overtemperature protection. The low current shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. Typical applications include high performance point of load regulation, notebook computers and high density and distributed power systems.
  • Low RDS (ON) power MOSFET switches 26mohm/19mohm
  • Adjustable switching frequency range from 200KHz to 1.6MHz
  • Current mode control
  • Synchronous to external clock range from 200KHz to 1.6MHz
  • Accurate voltage reference of 0.6V ±1%
  • Monotonic start-up into pre-biased outputs
  • Power good indicator
  • Selectable hiccup mode and latch-off mode under voltage protection
  • Operating temperature range from -40°C to 125°C
