The SiC530 is an integrated power stage solution optimized Thermally enhanced PowerPAK MLP4535-22L. for synchronous buck applications to offer high current, high package efficiency, and high power density performance. Packaged Vishay 's Gen IV MOSFET technology and a in Vishay 's proprietary mm x mm MLP package, low-side MOSFET with integrated Schottky SiC530 enables voltage regulator designs to deliver up to diode 30 A continuous current per phase. Delivers up to 30 A continuous current, 40 A at 10 ms peak The internal power MOSFETs utilize Vishay 's current state-of-the-art Gen IV TrenchFET technology that delivers High efficiency performance industry benchmark performance to significantly reduce switching and conduction losses.

2 High frequency operation up to 2 MHz The SiC530 incorporates an advanced MOSFET gate driver Power ON reset IC that features high current driving capability, adaptive 5 V PWM logic with tri-state and hold-off dead-time control, an integrated bootstrap Schottky diode, Supports PS4 mode light load requirement for IMVP8 with and zero current detect to improve light load efficiency. The low shutdown supply current (5 V, 5 A). driver is also compatible with a wide range of PWM. controllers, supports tri-state PWM, and 5 V PWM logic. Under voltage lockout for VCIN. A user selectable diode emulation mode (ZCD_EN#) Material categorization: for definitions of compliance function is included to improve the light load performance. please see The device also supports the PS4 mode to reduce power consumption when system operates in standby state.
