Block diagram of PDA Power Supply The flyback regulator generates a negative bias voltage (Nominally –12V) from the battery voltage. The output of the flyback generator is temperature compensated and adjusted under software control.
PAMS RAE-5 4. User Interfaces Technical Documentation QWERTY Keyboard Module UL8 General UL8 is the combined QWERTY keypad/flex connection module. The base flex is single–sided, so all the components are on the same side of the flex. Approximate component placement is shown below: AF8 PWB 70 pin connector 5469145 50 pin connector 5469817 Figure 6.
PAMS RAE-5 4. User Interfaces Technical Documentation AF8 PWB AF8 is a small additional PWB to achieve ”bulls eye” shaped pads for the earpiece and connection for the battery removal switch. (Check that the RAE-5 software supports the battery removal switch feature.) The approximate shape of AF8 is shown below. One 22pF SMD capacitor is assembled to the AF8. Figure 7.
