MK9218 100V Synchronous Buck DC/DC Controller 1 DESCRIPTION The MK9218 operates over a wide input voltage range from 6V to 100V. With appropriate high-side and low-side MOSFET and Inductance, the MK9218 delivers up to 30A output current. The MK9218 adopts a voltage mode control architecture to achieve excellent accurate voltage output. The switching frequency is adjustable up to 1 MHz, which also can be synchronized to an external clock source to eliminate beat frequencies in noise-sensitive applications. MK9218 support Forced-PWM (FPWM) and Diode Emulation Mode; FPWM operation eliminates switching frequency variation to minimize EMI, while user selectable diode emulation lowers current consumption at light-load condition.
