RichTek Technology Corporation Voltage Regulators - DC DC Switching Regulators RT6211AHGE

The RT6211AHGE is a synchronous step-down DC-DC converter capable of delivering up to 1.5A output current with an input voltage range of 4.5V to 18V. It operates at a switching frequency of 500kHz and utilizes an Advanced Constant On-Time (ACOT) control architecture, which enhances transient response and maintains a nearly constant frequency across varying loads and input voltages. The output voltage is adjustable from 0.8V to 6.5V, making it suitable for a variety of applications including set-top boxes, portable TVs, and access point routers. The device features integrated MOSFETs with on-resistances of 230mOc for the high side and 130mOc for the low side, contributing to its high efficiency. Protection mechanisms include cycle-by-cycle current limiting, output under-voltage protection, output over-current protection, and thermal shutdown. The RT6211AHGE is packaged in a compact SOT-23-6 format, which is compatible with both SnPb and Pb-free soldering processes. This product is ideal for engineers seeking a reliable and efficient voltage regulation solution for their designs.
