A 24V-to-1V Hybrid Converter With Adaptive Dead Time Control for Point-of-Load Applications

In this research, we introduce a hybrid power converter for point-of-load (PoL) applications. By separating the DC-DC converter into two stages, this hybrid converter achieves a voltage conversion ratio of D

/2. Therefore, 5V power transistors can be used in the main current path, which significantly increases efficiency. An adaptive dead-time control and an anti-shoot-through buffer are proposed to further enhance efficiency. With V

=24V and V

=1V, this converter achieves a peak efficiency of 94.5% at 1A output.
