Abstract
A non-inverting dual voltage regulation set point power supply for a restraint control module is disclosed that includes a main power source. A regulated voltage generation circuit connected with said main power source for generating a regulated output voltage having an upper set point and a lower set point. A buck switch connected to said main power source and said regulated voltage generation circuit for bucking the regulated output voltage generated by said regulated voltage generation circuit to said upper set point if said voltage supplied from said main power source is greater than said upper set point. A boost switch connected with said regulated voltage generation circuit for boosting the regulated output voltage generated by said regulated voltage generation circuit to said lower set point if said voltage supplied from said main power source is less than said lower set point.
