As USB PD 3.1 pushes the industry toward 48V/240W architectures, high-voltage output has become the new standard. This shift reduces output current and heat, making it perfect for powerful desktop chargers and industrial power supplies.
To handle these demands, Miracle Power has unveiled the MIR15N7P4S1GC, a 150V N-channel MOSFET designed to withstand the harsh voltage spikes and thermal stress of high-power operation. Housed in a PPAK 5×6 package, this chip is built for the next generation of compact, high-density fast-charging solutions.
The MIR15N7P4S1GC is engineered for peak performance, boasting a 150V breakdown voltage and a typical on-resistance of just 6.2mΩ. With a continuous current rating of 102A, it significantly lowers conduction losses and keeps the device running cooler. Its switching efficiency is equally impressive: with a 30nC total gate charge and 6.7nC Miller charge, it excels at high frequencies, improving system efficiency and simplifying EMI design.
In a 240W fast-charging prototype, the chip helped achieve a staggering 95.88% full-load efficiency. Even under extreme 264VAC input, the chip maintained a stable profile, proving its robust protection against switching transients and load surges.
Miracle Power’s new 150V MOSFET is a game-changer for power engineers tackling 48V designs. By combining low resistance, low gate charge, and a high Safe Operating Area (SOA), it effectively solves the stress issues common in high-voltage topologies. As the industry shifts toward high-density PD 3.1 power, Miracle Power’s latest flagship chip is a key component for manufacturers looking to build smaller, faster, and more reliable charging products.
