A single output PWMs is converted to high current push-pull circuit configuration using UC3706 dual output driver series is provide on below schematic. UC3706 is one of UC1706 dual output driver family which interface low-level control functions and such power MOSFET’s (a high power switching).

These UC1706, UC2706, and UC3706 implies three functions such as single-low-current digital input then activates a pair of high-current which can source to 1.5A each, an optional single-ended to push-pull conversion, and current imiting, automatic deadband control, and thermal shutdown protection.

For applications such as post switcher regulator, battery operated equipment and local on-card regulation the herein LM2991 low dropout adjustable negative regulator is a key component. This LM2991 said to be a short-circuit proof which may enhance the reliability of overloaded for long periods.

The circuit diagram above shows LM2991 negative low dropout adjustable regulator. Cin 10uF required if the LM2991 regulator is located more than 6 inches from the power supply capacitors. Then, you’ll need Co 10uF aluminium electrolytic or 1 uF solid tantalum for stability purpose, according to its datasheet.
