<p>➀ Diodes introduced four automotive-grade buck converters (AP68255Q, AP68355Q, AP6A255Q, AP6A355Q) supporting 48V rails, with input voltages up to 100V and output currents of 2.5A or 3.5A; </p><p>➁ The asynchronous design uses external Schottky diodes and features a constant on-time control scheme (～300kHz) for fast transient response and low ripple, alongside EMI-reduction techniques and proprietary gate drivers; </p><p>➂ Qualified to AEC-Q100 Grade 1, the converters include protection mechanisms (over-current, over-temperature) and industrial-grade variants, targeting automotive and high-power applications.</p>
