Does the Spice model of LTM4651 work?
I am using 4651 to make -12V from +24V but can't get the desired output.
The output is -0.6V with 0.5Vpp ripple and freq is about 15kHz but the switching freq is set to 1.1MHz.
All external parts have selected according to the datasheet.
Pls check the attached sch.
And how the output of 4651 can be controlled by DAC voltage like the VDAC pin of LTC2974 or similar?
