  The HT7463C/D is a current mode buck converter. With a wide input range from 4.5V to 60V, the HT7463C/D is suitable for a wide range of applications such as power conditioning from unregulated sources. Having a low internal switch typical RDSON value of 0.9Ω, the device has a good operating typical efficiency value of 85% and the added advantage of reduced junction temperature. The operating frequency is fixed at 1250/550kHz for the HT7463C/HT7463D respectively. The HT7463C allows the use of small external components while still being able to have low output voltage ripple. A soft-start function can be implemented using the enable pin and by connecting an external RC circuit allowing the user to tailor the soft-start time to a specific application.
