详情介绍：


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.
MK9218 is offered with wide duty cycle from 1% to 99% under appropriate switching frequency, so input and output voltage can easy to be choose.
The MK9218 provides a power good (PG) flag pin to indicate output voltage.
