The OKDx-T/20-W12 and the OKDx-T/25-W12 series are high efficiency, digital point-of-Load (PoL) DC-DC power converters capable of delivering 20A/66W.

Available in three different package formats, through-hole, single-in-line, and surface mount, these converters have a typical efficiency of 97.1%. PMBus™ compatibility allows monitoring and configuration of critical system-level performance requirements.

Apart from standard PoL performance and safety features like OVP, OCP, OTP, and UVLO, these digital converters have advanced features: digital current sharing (full power, no derating), non-linear transient response, optimized dead time control, synchronization, and phase spreading.

These converters are ideal for use in telecommunications, networking, and distributed power applications.
