5.9.3

+1.6V Switching Regulator

The +1.6V DSP core supply is sub-regulated from the +3.3V supply with 
another switching regulator, U910. This device is also a current mode 
controller and operates in a similar fashion to U900. It differs in that the 
output MOSFETs and current sense resistor are contained internally for 
reduced PCB area. Its higher operating frequency of 1.5MHz allows the use 
of a much smaller smoothing inductor, L910. An output filter, E910 and 
C949, and bulk capacitor C973, are provided, as for the +3.3V and +1.8V 
outputs.

5.9.4

Auxiliary Supply

An auxiliary supply is used to power some of the switching regulator internal 
circuitry, as well as providing the input to the +6V regulator (see 

“+6V 

Regulator” on page 84

). Some of the operating current for the U900 is 

derived from the auxiliary supply, through its EXTVcc supply pin.

With no voltage, or a low voltage, on EXTVcc, the power requirements for 
the internal circuitry of U900 are derived from the main +28V supply using 
an internal 7.5V(nominal) linear regulator. This normally occurs during the 
initial power supply startup phase. When the voltage on EXTVcc exceeds 
approximately 7.3V, an internal power switch disconnects the linear 
regulator from the internal supply rail, INTVcc, and the U900 internal 
circuitry draws its current directly from the auxiliary supply. Since the 
internal linear regulator no longer wastes power dropping the +28V input 
down to 7.5V, the overall power supply efficiency is increased, providing that 
the auxiliary supply is generated by a suitably efficient method.

The auxiliary supply is derived from the main +3V3 switcher using a charge 
pump voltage tripler circuit, comprising Q902, Q903, C921, C922, C930 
and D909-D911. The operation of this circuit can be explained by 
considering the voltage waveforms across the series combination of the 
filtering inductor L901 and sense resistor R908. When the switching 
regulator has reached a steady state, the voltage at the junction of R908 and 
C918 will be approximately constant at +3.3V, whereas the junction of L901 
and D905 will be switched between 0V and 28V by the action of chopper 
transistors Q901a and Q901b.

With Q901b conducting, capacitor C922 will charge from the +3.3V 
output via diodes D909a and D910b. Capacitor C921 will charge in a similar 
fashion through diodes D909b and D910a. When Q901a turns on (and 
Q901b turns off), the junction of L901 and D905 will be pulled up to +28V, 
reverse biasing D910a and D910b. Zener diode D908 will also be reverse 
biased; when it breaks down, MOSFETs Q903 and Q902 will turn on. 
Diodes D909a and D909b are also reverse biased during this process.

Note

In this circuit, n-channel MOSFETs Q902 and Q903 are operated 
in the reverse conduction mode, ie. positive current flow is from 
source to drain. The MOSFETs are operated in this mode 
because, in normal connection, the inherent substrate diode
