the routing is done. Table 5-1 illustrates example values of
Rsense for different currents.
The method to calculate the Rsense value for a desired average
current is explained in the application note, Floating Load Buck
Topology for HB-LEDs - AN52699
Figure 5-3. High Side Current Measurement
5.6 Voltage Comparators
There are six comparators that provide high speed comparator
operation for over voltage, over current, and various other
system event detections. For example, the comparators may be
used for zero crossing detection for an AC input line or
monitoring total DC bus current. Programmable internal analog
routing enables these comparators to monitor various analog
signals. These comparators include the following key features:
■ High speed comparator operation: 100 ns response time
■ Programmable interrupt generation
■ Low input offset voltage and input bias currents
Six precision voltage comparators are available. The differential
positive and negative inputs of the comparators are routed from
the analog multiplexer and the output goes to the digital
multiplexer. A programmable inverter is used to select the output
polarity. User-selectable hysteresis can be enabled or disabled
to trade-off noise immunity versus comparator sensitivity.
5.7 Reference DACs
The reference DACs are used to generate set points for various
analog modules such as Hysteretic controllers and comparators.
The reference DACs include the following key features:
■ 8-bit resolution
■ Guaranteed monotonic operation
■ Low gain errors
■ 10 us settling time
These DACs are available to provide programmable references
for the various analog and comparator functions and are
controlled by memory mapped registers.
DAC[0:7] are embedded in the hysteretic controllers and are
required to set the upper and lower thresholds for channel 0 to 3.
DAC [8:13] are connected to the Power Peripherals Analog
Multiplexer and provide programmable references to the
comparator bank. These are used to set trip points which enable
over voltage, over current, and other system event detection.
5.8 Built-in Switching Regulator
The switching regulator is used to power the low voltage (5 V
portion of the PowerPSoC) from the input line. This regulator is
based upon a peak current control loop which can support up to
250 mA of output current. The current not being consumed by
PowerPSoC is used to power additional system peripherals. The
key features of the built-in switching regulator include:
■ Ability to self power device from input line
■ Small filter component sizes
■ Fast response to transients
Refer to Table 15-20 for component values.
The 'Ref' signal that forms the reference to the Error Amplifier is
internally generated and there is no user control over it.
Figure 5-4. Built-in Switching Regulator
5.9 Analog Multiplexer
The PowerPSoC family’s analog MUX is designed to route
signals from the CSA output, function I/O pins and the DACs to
comparator inputs and the current sense inputs of the hysteretic
controllers. Additionally, CSA outputs can be routed to the AINX
block using this MUX.
For a full matrix representation of all possible routing using this
MUX, refer to the PowerPSoC Technical Reference Manual.
The CPU configures the Power Peripherals Analog Multiplexer
connections using memory mapped registers. The analog
multiplexer includes the following key features:
■ Signal integrity for minimum signal corruption
