This is circuit Switching power supply for MP3 player for automobile. It is powersupply that can be operated from the 12V battery of the car. The supply uses the Motorola MC33167T switching regulator operating at 72 kHz. And consists of a 5V/-5V section and a 12V/-12V section. This to use the small space in my enclosure more flexible.
I See circuit on website many. I link good site :http://home.concepts-ict.nl/~cybersake/carmp3/ about Supply for MP3player. Very good for all user.
Detail in web::
I worked on a project to build an MP3 player for my automobile. I needed a PC powersupply that can be operated from the 12V battery of my car. I studied some datasheets and rolled my own switched mode power supply (SMPS). The supply operates with a battery voltage of 7.5V to 20V (Limited by a transiënt suppressor). The supply can be used with a 24V battery when you replace the transiënt suppressor by a 30V type. The 12V and -12V section has a nice feature: It operates in step-up mode when the input voltage goes below 12V. My supply uses the Motorola MC33167T switching regulator operating at 72 kHz. The supply consists of a 5V/-5V section and a 12V/-12V section. This to use the small space in my enclosure more flexible.
