Automotive LED Driver Simulation Sheds Light on MOSFET Switch Behavior
June 4, 2020
 |
By: John Christopher Rice Principle MTS, Field Applications; Maxim Integrated |
Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time required to heat the filament of an incandescent bulb and are especially useful in brake lamps, where fractions of a second matter. The challenge in designing an automotive LED lamp is in satisfying government requirements for light output while also being cost effective. Another hurdle is design complexity where a switch-mode power supply (SMPS) is often required. A SMPS is more complex, expensive, and can be a source of electromagnetic interference (EMI), especially in comparison with the body control module (BCM) high-side-driver (HSD) that is typically used to turn on an incandescent bulb. Generating sufficient light output often requires a series string of LEDs. Consequently, a boost converter is often used to create the LED string comp

Understand the Multiphase Buck Voltage Regulator Advantage
May 26, 2020
 |
By: Reno Rossetti Power Blogger, Maxim Integrated |
Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the output during the entire cycle. The higher delivery of current to the output, per cycle, makes the buck converter the most efficient architecture. As one of many examples, modern microprocessors, from those used in powerful server blades to smartphones, operate with very low input voltages, making the buck converter the necessary power source. As these applications grow in sophistication, the power source has to beef up its power delivery while stepping up its efficiency to reduce heat losses. Accordingly, the buck converter has evolved from non-synchronous to synchronous switching and from a single-phase device that delivers a few hundred milliamperes of current to a multiphase device that can successfully deliver tens to hundreds of amperes of current.
How a Small Schottky Diode Minimizes Noise in Synchronous Converters
May 21, 2020
 |
By: Ray Crampton Guest Blogger, Ray Crampton Consulting |
Every switching supply designer becomes keenly aware of the need to design for noise and the tug of war this has with efficiency, board space, cost, and development time. The body diode present in MOSFETs used in synchronous converters is a wonderful freebie—it provides the conduction path during dead time commutation. Also free is the noise it generates, which is not the kind of "free" we want more of. Let's look at what's going on, explore how a small Schottky diode can help minimize noise, and develop some understanding of when and how this technique would be helpful.

How Capacitors Provide a Window into the Real Value of a Battery
May 5, 2020
|
By: Reno Rossetti Power Blogger, Maxim Integrated |
Capacitors, with their ability to store charge and deliver it quickly on demand, are essential components in power conversion. Output capacitors readily supply a sudden load increase, while the voltage regulator control loop reacts slowly to the sudden demand. Input capacitors present the power source with a smoother load by averaging the voltage regulator's current peak demand. Supercapacitors complement ordinary power sources like batteries in supplying fast varying loads, which the battery would be unable to supply due to its high impedance. And supercapacitors can replace backup batteries in low-dissipation applications in which typical power outages last from a few seconds to several hours.

How LiDAR Delivers Critical Distance-Sensing for Self-Driving Cars
April 17, 2020
 |
By: Bonnie C. Baker Blogger, Maxim Integrated |
If you're designing autonomous vehicle applications, you know how important LiDAR (light detection and ranging) is. A critical optical technology that executes autonomous vehicle distance-sensing, LiDAR is an important part of advanced driver assistance systems (ADAS) and essential for self-driving cars. Its performance depends on the optical front-end, as well as how the signal is transmitted through the signal chain and then processed. An important component in this signal chain is the transimpedance amplifier (TIA). In this blog post, I'll provide an overview of how LiDAR works and discuss what to look for in an effective TIA.
In LiDAR applications, a laser light nanosecond pulse burst is sent from a source and reflected from objects in the view. The reflected light is detected, and the time of flight (ToF) creates a distance map of the objects in the view.

Getting to Reliable Sensor Data: Interaction Between Electronics, Optics, and Mechanical Design
January 15, 2020
|
By: Ian Chen Executive Director, Industrial & Healthcare Business Unit, Maxim Integrated |
Getting reliable sensor data is complex. For example, an optical heart-rate sensor is actually sensing the changes in an electric current. Heartbeats cause the volume of arterial blood to change synchronously with each pulse. The change in volume changes the amount of light absorbed and reflected as it travels through live tissue. When that light exits the tissue and enters a photodetector, it changes the output current. By creating a sensing system that carefully sets up a proper series of “dominos,” a current sensor becomes a heart-rate sensor.

By: Travis Taylor Applications Engineer, Advanced Sensor Products, Maxim Integrated |
Wearable and handheld electronic design comes with an inherent tradeoff between battery life, feature richness, and size. To fit the most features in a small device, you want the smallest, most efficient power management scheme. For simple battery-powered devices, all you often need is a diode ORing. A diode ORing powers the device from the battery when unplugged and switches to the charging cable when plugged in. This simple scheme uses two diodes to select the option with the higher voltage. However, diodes have an inherent tradeoff between forward voltage, leakage, size and cost, where you generally get to pick two.
