AN805 Datasheet (Vishay Siliconix) - PWM Optimized Power MOSFET

AN805, PWM Optimized Power MOSFET

AN805 Vishay Siliconix PWM Optimized Power MOSFETs for Low-Voltage DC/DC Conversion Designers of low-voltage dc-to-dc converters have two main concerns: reducing size and reducing losses.

As a way of reducing size, designers are increasing switching frequencies.

But the result has been reduced converter efficiency.

To minimize losses, MOSFET manufacturers have generally focused on lowering on-resistance.

But the results have not been optimal for dc-to-dc conversion designs, since gate charge an
