CHOOSING THE PROPER PARAMETERS IN FREQUENCY SPREAD SPECTRUM (FSS) DESIGNARTICLEThe frequency spread spectrum (FSS) technique has been widely applied in power converters to reduce electromagnetic interference (EMI) noise. However, in practice, there are multiple parameters in FSS design that must be considered to optimize EMI performance with minimal side effects. This article introduces FSS parameters such as modulation shape, frequency, and depth, and analyzes their impact ...

USING A SMART IDEAL DIODE FOR CAR BATTERY FRONT-END PROTECTIONARTICLEIf the battery terminals in a car are reverse-connected during a jump start, vehicle maintenance, or repair, the components in the electronics control unit (ECU) may be damaged if they cannot handle this fault condition. On top of this, during normal operation the car battery voltage is not constant — the input voltage (VIN) can even be negative under several transient tests regulated by the EMC s...

SWITCH-NODE WAVEFORM DEFINES EMC CHARACTERISTICS FOR STEP-DOWN CONVERTERSARTICLEStep-down converters’ switch-node voltage waveform defines the electromagnetic compatibility (EMC) behavior for automotive CISPR 25 Class 5 measurements. The ringing frequency in the switch-node waveform is an important signal on the EMC receiver, where a higher ringing amplitude on the switch node often causes EMC issues. Understanding the switch-node waveform enables predicting the converter’s E...

THE BENEFITS AND LIMITATIONS OF USING FSS IN MODERN SMPS DESIGNSARTICLEModern passenger vehicles are not only made to carry passengers from one destination to the next — they must also function as communication tools, TVs, home cinema sets, LED illumination centers, and even massage parlors. The customer’s focus is changing from purely driving characteristics (e.g. horsepower and acceleration) to include entertainment systems, such as the size of the multimedia touch...

COMPARING THE THERMAL BEHAVIOR OF 6A DEVICES ON A TWO-LAYER AUTOMOTIVE PCB DESIGNARTICLEThe rated current is a typical parameter for DC/DC converters, and the maximum possible ambient temperature (TA) depends on the PCB size and the IC’s thermal resistance. In this article, an automotive expert will examine the thermal behavior of MPS’s MPQ4326-AEC1 compared to a traditional 6A device on a small, 2-layer PCB (60mmx40mm). The planned production costs and the PCB size determine the ...

OPTIMIZING AUTOMOTIVE APPLICATIONS WITH ZERO-DELAY PWM CONTROL (ZDP)ARTICLEThe increasingly high power consumption for rails in advanced driver-assistance systems (ADAS) and digital cockpit applications calls for an improved control scheme from traditional control methods (e.g. peak current mode control), with a need for excellent load transient performance and low on-time capabilities. While constant-on-time (COT) control can be utilized as a control scheme, its varied ...

ADVANCING OPTICAL MODULES FOR DATA TRAFFIC WITH MPS MODULESARTICLEData traffic is the center of modern life, with any mobile phone app nowadays requiring tens of hundreds of megabytes for installation packages. When several software updates are made, it is necessary to be connected to Wi-Fi. Loading a page while online shopping consumes several megabytes of traffic to load a single page, and video calls are prone to freeze if the Internet speed is not fast enoug...

ANALYSIS AND MODELING METHOD FOR EMI OF NON-ISOLATED CONVERTERS (PART II)ARTICLEWhen not addressed in the earlier design stages, electromagnetic interference (EMI) can make it difficult for parts to meet EMI requirements in the final design stages. Being able to model and analyze EMI helps designers optimize for EMI and predict EMI at the start of their design. There are two types of EMI: conducted EMI and radiated EMI. Conducted EMI is transmitted via physical contact (to t...

ANALYSIS AND MODELING METHOD FOR EMI OF NON-ISOLATED CONVERTERS (PART I)ARTICLEWhen designing an electronic system, ensuring the device meets electromagnetic compatibility (EMC) standards is crucial — not only because of the requirements placed by legislative bodies, but also because electromagnetic interference (EMI) can lead to instability and unwanted behavior. Since EMI testing usually takes place in the final design stages, being able to model and analyze EMI can effect...

WORKING PRINCIPLES FOR SELECTING A BOOST CONVERTERARTICLEConverter selection is the first step in power supply design that directly impacts stable system operation and performance. Typically, the designer must determine whether a power converter meets the actual load capacity based on the rated current value. For example, selecting a 36V/3A buck converter for a 24V to 5V/2A power rail achieves excellent efficiency, temperature rise, and cost performanc...
