    Products Detail

    The RT6212A/B is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 4.5V to 18V input supply. It adopts ACOT architecture to improve transient response and maintain constant frequency. Features include integrated 163mΩ/86mΩ MOSFETs, cycle-by-cycle current limit, soft-start to eliminate input current surge, output under-voltage protection, over-current protection, and thermal shutdown. The device requires minimal external components and comes in a compact TSOT-23-6 package.

    Key Features

    • Integrated 163mΩ/86mΩ MOSFETs, 4.5V to 18V Supply Voltage Range, 500kHz Switching Frequency, ACOT Control, Feedback Reference Voltage 0.8V ±1.5% or 0.765V ±1.5%, Internal Start-Up into Pre-Biased Outputs, Compact Package: TSOT-23-6 Pin, Input Under-Voltage Lockout, Over-Current Protection and Hiccup
