MK9218
MK9218
100V Synchronous Buck DC/DC Controller

应用:

·     POL modules

·     High-Power Density DC – DC

·     Datacom, Telecom

·     Non-isolated PoE and IP cameras


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.
