High frequency and high efficiency switching power supplies, such as VRM, VRD, POL, DC-DC converters, and high current flat DC-DC converters, have certain requirements for their dedicated MOSFET gate drivers, such as low conduction resistance, high load current, and fast switching speed, in order to reduce switching losses and improve power conversion efficiency.
The SLM27211 series integrates a 120V withstand voltage diode, supporting high-frequency and high current output, and can drive MOSFETs in a wide voltage range of 8V to 17V. Since its launch on the market, the SLM27211 series has been widely used in multiple types of modular power supplies due to its high safety and reliability.
Compared with similar products, the SLM27211 series has a smaller volume, higher withstand voltage value (120V), lower negative pressure value (-30V/200ns), and higher dV/dt value (70V/ns). Effectively empowering various terminals based on MOSFET products, supporting the rapid development and reform and innovation of the industry.
