Sample & Buy ® RT6234A/B 3A, 18V, 500kHz, ACOTTM Step-Down Converter General Description Features The RT6234A/B is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 3A output current from a 4.5V to 18V input supply. The RT6234A/B adopts ACOT architecture to allow the transient response to be improved and keep in constant frequency. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault conditions also include output under voltage protection and thermal shutdown.        Ω / 70mΩ Ω MOSFETs Integrated 130mΩ 4.5V to 18V Supply Voltage Range 500kHz Switching Frequency ACOT Control 0.8V ± 2% Voltage Reference Output Adjustable from 0.8V to 6.5V Monotonic Start-Up into Pre-Biased Outputs Applications  Ordering Information  RT6234A/B   Package Type QW : WDFN-8L 2x3 (W-Type)  Lead Plating System G : Green (Halogen Free and Pb Free) Set Top Box Portable TV Access Point Router DSL Modem LCD TV Pin Configuration BOOT GND SW VIN A : PSM Mode B : PWM Mode 1 2 3 4 GND (TOP VIEW) UVP Option H : Hiccup 9 8 7 6 5 SS PGOOD EN FB Note : Richtek products are :  WDFN-8L 2x3 RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.  Suitable for use in SnPb or Pb-free soldering processes.
