High-Accuracy Op Amp Boasts Energy Efficiency

STMicroelectronics has announced the TSV7722, a precision high-bandwidth op amp, with gain-bandwidth of 22MHz and slew rate of 11V/μs. It is well-suited for high-speed signal conditioning and accurate current measurement in power-conversion circuits and optical sensors. The maximum input-offset voltage of 200µV and extremely low input-voltage noise density of 7nV/√Hz permit accurate low-side current measurements.

Buffer Modules Offer Extra 380ms Hold-Up Times

TDK has announced the introduction of the TDK-Lambda brand ZBM20 12V, 15V and 24V 20A rated open-frame buffer modules. The ZBM20 series provides an extended 380ms hold-up time to power supplies preventing data loss during brief power interruptions or allowing equipment to safely shutdown. Applications include industrial automation, robotics, test, communication and more.

Synchronous Inverting Converters Shrink Board Space

Maxim Integrated has introduced the MAX17577 and MAX17578 which the company claims are the industry’s smallest, highest-efficiency synchronous inverting DC-DC step-down converters. As Maxim’s first 60V inverting DC-DC converters with integrated level shifters, these devices save up to 72% of board space by reducing component count by half while using 35% less energy than the closest competitive solutions, says Maxim.

Voltage Regulators

Voltage regulators are a key technology for managing the heat dissipation in an electronic system. In this article, Jeff Bachiochi takes you through the evolution, science and functionality of voltage regulators. He looks at the heat and efficiency characteristics of voltage regulators, and compares linear versus switching technologies.

Low Cost 8W DC-DC Converters Feature 1”x1” Package

RECOM announces its REC8E range of low cost, 8W DC/DC converters in a 1”x1” package with three input ranges including 20-60VDC to suit 48V Li-ion batteries and LV 148 applications. The converters are specially designed for battery-powered applications. Three input voltage ranges are available: 9-18V (12V systems), 18-36V (24V systems) and 20V-60V (48V systems), the latter matching the LV 148 requirements for 48V Li-ion voltages in vehicles.
