Apart from standard PoL performance 0.6 V - 3.3 V output voltage range ciency, digital point-of-Load (PoL) DC-DC and safety features like OVP, OCP, OTP, and power converters capable of delivering UVLO, these digital converters have advanced High ef ciency, typ. 97.2% at 5Vin, 3.3Vout half 50A/165W. Available in three different pack- features: digital current sharing (full power, load age formats, through-hole, single-in-line, no derating), non-linear transient response, Con guration and monitoring via PMBus and surface mount, these converters have a optimized dead time control, synchronization, Adaptive compensation of PWM control loop & typical ef ciency of 97.2%.
