High frequency and high efficiency switching power supplies such as VRM, VRD, POL, DC-DC converter, high current flat DC-DC converter and other applications，There are certain requirements for the special MOSFET gate driver，Such as low on-resistance, large load current, fast switching speed，To achieve the purpose of reducing the switching loss and improving the power conversion efficiency。
The SLM27211 series integrates a 120V voltage resistant diode, supports high frequency and high current output, and can drive MOSFETs in a wide voltage range of 8V~17V。Since its introduction to the market, SLM27211 series has been widely used in many types of module power supplies due to its high safety and reliability。
SLM27211 series is smaller than similar products with higher withstand pressure value (120V), lower negative pressure value (-30V/200ns), higher dV/dt value (70V/ns)。Effectively enable all kinds of terminals based on MOSFET products to help the rapid development and reform and innovation of the industry。
