I was wondering if there was a spec for the minimum load current for the PTN78000H?
My application for the PTN is a pwm heater circuit. The pwm frequency is 2Khz, with a duty cycle from 0-100%.
Vi=+24V, Vo=12V. A fet will be used to switch the current, driven by the pwm.
I am not too concerned with output voltage regulation/noise, more concerned with effiency, especially at low duty cycles.
Any recommendations beyond careful selection of the input and output capacitors? Concerns?
Thank you in advance for any help.
