    Power Supplies VSNUB VRAW 3.3V 1.2V Bose Brand FET U50, U51 U902, Q9031 Quasi-Regulator Power Supply Block Diagram Bass module rectifies un-regulated power VSNUB from the secondary of the line power transformer. VSNUB is, in turn, converted to the various other potentials required by the system. Nominally 26VDC, this voltage varies with load and line levels, but is limited to 31.5V maximum(assuming line voltage of 140V AC).

  • Page 37: Power Supply Vsnub

    Power Supply VSNUB From Transformer To 3.3 V Regulator VSNUB VSNUB is formed by rectifying the transformer secondary potential via power rectifiers D10-D13. An additional rectifier, D16 prevents discharge of the filter capacitor, C48 through the FET switch, Q10, whenever this switch is on.

  • Page 38: Power Supply Vraw

    Power Supply VRAW From Transformer To 3.3 V Regulator VRAW Vraw provided power to the Audio Power Amplifiers, U150, U150, U350, and the +5V regulator. Its potential is monitored by the DSP, U7000, via the circuit associated with VRAWSEN. When active the potential can vary from 12 vdc to 14.0 vdc.

  • Page 39: Power Supply 5V And 10V Regulators

    Power Supply 5V and 10V Regulators From Transformer To 3.3 V Regulator The only internal power requirement for 5 volts are the CODEC, U4000, power supply and the current source for the ramp circuit formed by Q6201 and R6207. The source for the +5V linear regulator, U11, is Vraw. +5V is provided only when Vraw is enabled.

  • Page 40: Power Supply 1.2V Regulator

    Power Supply 1.2V Regulator 1.2V The processing core of the DSP is the sole consumer of the 1.2 volt power supply. Its relatively high current consumption requires efficient power conversion. The Texas Instruments TPS40055, U50, provides the PWM control functions for a synchronous-rectifier power circuit. U51 is a dual N-channel FET used as switch transistor and synchronous rectifier for the buck regulator circuit.

  • Page 41: Power Supply 3.3V Regulator

    Power Supply 3.3V Regulator 3.3V The USB controller, U6000, the I/O circuitry of the DSP, U7000, and the digital processing portions of the CODEC, U4000 all require power from +3.3V. This circuitry is biased both during normal operation and stand-by, so no enable control is required.

  • Page 42: Sensor And Power Failure Detection

    Sensor and Power Failure Dectection USB Controller Out to Control Sensor SENSOR is generated by switching the +3.3 volt supply via Q6102. SENSOR powers the touch sensor in the control module. switching SENSOR off momentarily forces the control module touch sensor to reset, forcing its output to the muted state.

    U6000. R8002 provides the necessary pull up to the D+ line in order to signal to the host that the Companion 5 is present and is a full-speed device. The resistor divider R6011 and R6013 permits U6000 to sense the presence of the USB5V signal from the host.
  • Page 44 The TAS1020 contains an internal ROM and all Data and Program RAM. An external EEROM, U6002, stores the portion of the program code custom to the Companion 5 application. Once the TAS1020 has come out of reset, it will read the code stored in U6002 via the Inter Integrated Circuit (I2C) communications path on pins 43 and 44.

    Digital Signal Processor USB Controller To DSP Pin 14 The Texas Instruments TMS320DA705 (U7000) is a floating-point Digital Signal Processor with internal ROM and 192kbytes of internal RAM. No external RAM is required or supported by this processor. The internal ROM includes a boot loader algorithm that permits booting the custom application portion of the program code from a variety of external devices.

  • Page 48: Conversion And Ramp Generation

    Conversion and Ramp Generation Analog inputs Several signals monitored by the DSP are analog in nature. One of the two Advanced Serial Processor (McASP) engines that are available in the DSP is used to perform the analog to digital conversion with the aid of several external components.
  • Page 49 Ramp Calibration Ramp Calibration In order to calibrate the Analog to Digital Conversion, the DSP uses a general-purpose i/o pin to overdrive the analog VRAWSEN signal present at the comparator input U6200.9 for the duration of a conversion cycle. This forces the input to +3.3 volts.
