Linear Technology has announced the LT3932, a monolithic, synchronous, step-down DC-DC converter with internal 36V, 2A power switches and an internal PWM generator. Its fixed frequency, peak current mode control accurately regulates current within ±1.5% for strings of up to 2A LEDs. Its integrated PWM generator offers a 128:1 dimming ratio. The device’s 3.6V to 36V input … [Read more...]
Top Three EMI and Power Integrity Problems with On-Board DC-DC Converters and LDO Regulators
Co-authored by: Kenneth Wyatt and Steve Sandler INTRODUCTION Modern devices are continuing a long-term trend of squeezing more electronics into smaller packages, while also increasing system performance, data rates and operating efficiency. Higher efficiencies are often achieved by implementing faster silicon MOSFETs or even faster eGaN FETs while size is reduced by … [Read more...]
Ultra Low Noise Pluggable PSUs

Expanded EMC Cable Fittings
LUTZE Inc. expands its industrial cable fitting offering and introduces large diameter EMC (Electro Magnetic Compatibility) fittings to include sizes for large diameter cables up to 500MCM (75mm OD). These NPT and metric thread fittings provide effective strain relief and 360° shield termination. They use the same clamp style shield termination method as our smaller EMC … [Read more...]
Nickel-PTFE-Nanodiamond Coatings with Improved Abrasive Wear Properties Developed
Nanodiamond material specialist Carbodeon of Finland has worked with metal finishing specialist CCT Plating of Germany, to develop a new electroless nickel, PTFE and nanodiamond composite coating. Electroless nickel-PTFE (EN-PTFE) coatings provide excellent anti-adhesive and low friction properties but are traditionally soft and wear quickly in abrasive conditions. By adding … [Read more...]
Troubleshooting ESD in Floating Medical Grade Circuits
Introduction Medical devices must be designed with proper isolation of patients from earth. For that reason all medical products have floating circuits. This means that the circuit ground is isolated from the earth ground. ESD protection in floating circuits with isolated grounds can be very challenging. Sometimes conventional ESD protection methods may not work. It is … [Read more...]
