This reference design is a synchronous buck converter for automotive applications utilizing a synchronous buck controller with frequency spread spectrum. The design uses a dual MOSFET in power SO-8 package. Forced pulse width modulation (FPWM) or diode emulation mode (DEMB) is jumper selectable. The features include an enable input and power good flag. The switching frequency is set to 440 kHz. Frequency dithering and input filtering help improve EMI performance. Modified frequency compensation supports all ceramic output capacitors.
