Keywords : Power management IC, buck‑boost converter, machine‑learning control, IoT, ultra‑low‑power, dynamic frequency scaling. The IoT ecosystem now exceeds 30 billion connected devices, many of which are constrained to sub‑milliwatt power budgets and operate on small coin‑cell or thin‑film batteries [1]. Conventional power‑regulation techniques—linear low‑dropout regulators (LDOs) for low‑noise needs and buck‑boost converters for wide input‑output ranges—each excel in a narrow operating regime but suffer from either high quiescent current (LDO) or sub‑optimal efficiency during low‑load periods (buck‑boost) [2,3].

– A zero‑voltage‑transition (ZVT) driver ensures that the MOSFETs turn on/off when their drain‑source voltage is near zero, suppressing shoot‑through. A soft‑switch capacitor C_ZVT stores the gate charge, enabling sub‑nanosecond turn‑on times. 3.2 Adaptive Controller (ACC) The ACC is implemented in a 6‑bit micro‑coded finite‑state machine (FSM) operating at 500 kHz. Its three functional units are: [ \hatI load[k+1] = \sigma
