According to the latest data, the global personal smart audio market will further grow in 2025, with an expected growth of about 8% compared to 494 million units in 2024, reaching a shipment volume of 533 million units. This market growth means that the audio power supply market will necessarily grow synchronously. How to select the right MOSFET to enhance the product competitiveness of your own audio power supply?

When considering this issue, let's first look at some models commonly used in audio power supplies, such as IRF1404PbF, CS1404, HY4004, FTP1404, etc. Although the above products are indeed good to use, to make the supply chain more stable, it is better to choose products with better localization.

Therefore, today Feihong Semiconductor will introduce to you a 250A, 45V MOSFET product, which can replace the aforementioned products for use and has high reliability.

The FHP1404V MOSFET. Why recommend it? Because compared with IRF1404PbF, it reduces conduction loss, has smaller gate charge (160nC vs 210nC), faster switching speed, and provides a higher cost-effective domestic alternative product.

Compared with CS1404, it has better on-resistance, suitable for products that pursue extreme efficiency and current capability.

Looking at the specific parameters of the FHP1404V field-effect transistor: Vgs(±V): 10; VTH(V): 3; ID(A): 250A; BVdss(V): 45V. RDS(on) = 2.5mΩ(max)@VGS=10V, RDS(on) = 1.95mΩ(typ)@VGS=10V.

Based on these parameters, the FHP1404V field-effect transistor is suitable for DC-DC push-pull topology boost circuits in 12V input audio power supplies.

The FHP1404V has passed 100% EAS test, 100% Rg test, 100% DVDS instantaneous thermal resistance test, etc., and adopts refined grading of Vth, further improving product consistency.

At the same time, by adopting the unique trench process and combining excellent packaging BOM materials, the product has high reliability and fast switching speed.

With the market growing rapidly, if there are selection problems during R&D, feel free to communicate and exchange ideas. For the selection of 250A, 45V MOSFETs for audio power supplies, it is recommended to use the FHP1404V field-effect transistor.
