Current Limit

• 125% of full load typical

Isolation

• 100 megohm minimum at 500 V

Conversion Frequency

• 250 kHz typical

Inhibit Pin Voltage (unit enabled)

• 10 V typical

Input Voltage Range

• MTO12XXT 9 to 16 VDC continuous

• MTO28XXT 16 to 36 VDC continuous

• MTO12XXT 25 V for 50 msec transient

• MTO28XXT 50 V for 50 msec transient

Case Operating Temperature (Tc)
