Description
RT6213A/B 3A Peak, 18V, 500kHz, ACOTTM Step-Down Converter General Description The RT6213A/B is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 3A peak output current from a 4.5V to 18V input supply. The RT6213A/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, output over current protection, and thermal shutdown. Ordering Information RT6213A/B Package Type J6F : TSOT-23-6 (FC) Lead Plating System G : Green (Halogen Free and Pb Free) UVP Option H : Hiccup PSM/PWM A : PSM Mode B : PWM Mode Note : Richtek products are :  RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.  Suitable for use in SnPb or Pb-free soldering processes.
