    Design a second-stage filter for sensitive applications

    Certain applications, such as test and measurement , are sensitive to voltage ripple and routinely require very low output voltage ripple. For example, 10µV/V of ripple ratio translates to 100dB of attenuation. Since it’s impractical to attain this level of attenuation using a buck regulator with a single-stage filter, a powerful design technique to reduce output voltage ripple is to use a second-stage...

    Local Interconnect Network – the last mile network

    When someone says “local network,” you may imagine the internet, a local area network (LAN), Wi-Fi® or Ethernet. While these technologies are robust and widespread, they require significant overhead – whether that’s wirele...

    How to Select a MOSFET – Part 1

    In complicated power designs, metal-oxide semiconductor field-effect transistor (MOSFET) selection has a tendency to be somewhat of an afterthought. After all, it’s just a three-pin device. How complicated can it be, right? But as anyone who enjoys raw oysters will (try to) tell you, appearances can be deceiving; trying to select the correct MOSFET or “FET” can be a task more complicated than you might...

    Powering a 12V bus with 24V batteries in automotive applications

    24V systems are common in commercial trucks, including heavy-duty pickup trucks, as well as military vehicles that require extra power. Converting power from 24V batteries to 12V for low-voltage electronics inside a vehicle cockpit necessitates the use of a DC/DC converter with a wide input-voltage range, fast load transient response and complete system protection, as shown in Figure 1. Figure 1: 24V automotive...

    When and how to supply an external bias for buck controllers – part 3

    In part 1 of this series, I discussed the need for an external bias and under what conditions you need to consider one. In part 2 , I discussed whether you can apply an external bias to any controller. In this third and final installment, I will go over a circuit that you can use to generate an external bias for any controller. This may prove useful in cases where a 5V bias rail is not available for providing the external...
