Bipolar +/- 15V and 5V from Car Battery supply

Bipolar +/- 15V and 5V from Car Battery supply
This DC to DC Converter use Max 541 from Maxim, IC1 is a switching regulator that generates a 45-kHz signal that drives the gate of MOSFET Q1 BUZ71A from Motorolla. The source of this power supply comes from a 12V car battery voltage. This DC to DC converter have an output  +-15V and 5V. (more…)
