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 16-20 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 Table 5-1.
