PE24111 Document Category: Product Specification 3.3 VIN, 20A, Two-stage Buck Regulator for Low Output Voltage Applications General Description The PE24111 is a compact, low-profile, and ultrahigh efficiency step-down DC-DC converter solution capable of delivering 20A output current from an input voltage range from 3.0–3.6V. The output voltage is set between 0.35V and 0.7V with external feedback resistors and can be adjusted by an external AVS DAC. Based on pSemi advanced two-stage architecture, the PE24111 consists of a two-phase interleaved charge pump followed by an interleaved buck regulator stage. This power system greatly reduces the inductance necessary for high efficiency while maintaining a small solution size for small-footprint and heightconstrained applications.
