Notes

1. All voltages are with respect to ground. Currents are positive into, negative out of specified terminal.

2. All ground pins soldered onto a 20 cm2 PCB copper area with free air convection, TA = +25°C.

3. Not covered by final test program.

4. Switching duty cycle D = 30%, f = 26.5 kHz.

s

5. External resistors RB for lowering of saturation voltage.
