Synchronous dc-dc converters boast super-wide input range, reduction in component count
The MAX17577 and MAX17578 from Maxim Integrated Products, Inc. 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 percent of board space by reducing the component count by half while using 35 percent less energy than the closest competitive solutions. […]
300-W/20-A buck-boost dc-dc converters optimized for 24-V inputs
TDK Corporation announces the addition of 20A 300W rated models to the i7C non-isolated DC-DC converter series. These buck-boost board mount power modules have been optimized for 24V input with a range of 9 to 36Vdc and can be adjusted from 8 to 24V. The i7C topology enables a seamless transition from buck (voltage reduction) […]
Isolated gate driver safely controls SiC MOSFETs
Joining STMicroelectronics’ STGAP family of isolated gate drivers, the STGAP2SiCS is optimized for safe control of silicon carbide (SiC) MOSFETs and operates from a high-voltage rail up to 1200V. Capable of producing a gate-driving voltage up to 26V, the STGAP2SiCS has a raised Under-Voltage Lockout (UVLO) threshold of 15.5V to meet the turn-on requirements of SiC […]
Current-compensated ring core chokes suppress common-mode interference
TDK Corporation presents a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interferences. These chokes are available in three sizes with current handling capacities between 10 A and 17 A, and with a rated voltage of 250 V AC (50/60 Hz). Depending on the type, the inductance value is between […]
Boost converter, LDO ICs feature supe-low quiescent currents
Designers can now extend battery life and reduce the solution size of consumer, industrial, healthcare, and IoT systems with three new Essential Analog ICs from Maxim Integrated Products, Inc. The MAX17227A 2A nano power boost converter, the MAX17291 high voltage, 1A boost converter, and the MAX38911 500mA LDO all provide the lowest quiescent current among competitive solutions to […]
New technology allows power transfer across glass panes
Through a bespoke conductive lamination process, ElectroglaZ technology delivers power to any point across a glass surface without the use of wires. The glass is formed by multiple layers separated by a transparent insulator; these layers work in tandem to form a complete circuit. Power can be delivered to almost any low-power application under 50 […]
Step-down switching regulators are drop-in replacements for inefficient SIP-3/TO-220 models
