Step-down regulator operates from 24-to-48-V inputs, emits little EMI
Analog Devices announces the Power by Linear LTM4653, 58VIN step-down µModule Regulator. The LTM4653 can safely operate from unregulated or fluctuating 24V to 48V input supplies in noisy environments such as factory automation, industrial robotics, communication infrastructure and avionics systems. The LTM4653 integrates input and output filters in a package, enabling the device to meet the EN55022 […]
High-efficiency step-down switching regulators handle 2 A
TRACO POWER has announced the new TSR 2 series of step-down switching regulators that are drop-in replacement for inefficient LMxx linear regulators. A high efficiency up to 96 % allows full load operation up to +67°C ambient temperature (full-load) without any heat-sink or forced cooling. The TSR 2 switching regulators provide significant features over linear […]
Boost regulator delivers wide input and output range and tiny footprint to optical modules
Analog Devices, Inc. announced the Power by Linear LTM4661, a low power step-up µModule regulator in a 6.25mm x 6.25mm x 2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm² single-sided or 0.5cm² on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, […]
Tiny LDO targets IoT apps with 300-nA quiescent current
STMicroelectronics’ STLQ020 low-dropout voltage regulator relieves the familiar trade-offs between quiescent current, output power, dynamic response, and package size, to give designers extra freedom. By combining small size with high performance and energy efficiency, the STLQ020 is ideal for use in battery-powered consumer products like smartphones and tablets, smart watches, audio or media devices, and wearables. It […]
DC-DC buck regulator modules operate over 4 to 42-V input range, come in ultra-small packages
Designers working on space-constrained applications can now dramatically reduce solution size and increase efficiency with the family of micro system-level IC (“uSLIC”) modules from Maxim Integrated Products, Inc. The MAXM17532 and MAXM15462 ultra-small (2.6mm x 3.0mm x 1.5mm), integrated DC-DC power modules are part of Maxim’s extensive portfolio of Himalaya power solutions that enable industrial, healthcare, communications, and consumer […]
Wide-VIN synchronous DC/DC buck regulators generate little EMI
Texas Instruments introduced two families of wide-VIN synchronous DC/DC buck regulators with industry-leading electromagnetic interference (EMI) and thermal performance. The highly integrated 5-A and 6-A LM73605/6 and 2.5-A and 3.5-A LM76002/3 step-down voltage converters feature an optimized pinout and best-in-class thermal coefficient to simplify the process of achieving EMI compliance and higher reliability for rugged industrial and […]
Dual 15-A/single 30-A µmodule regulator with stacked inductor package is 96% peak efficient
Analog Devices announces the Power by Linear LTM4662, a dual 15A or single 30A step-down µModule regulator in a BGA package with an exposed stacked inductor for improved thermal dissipation properties. The remaining components, the MOSFETs, DC/DC controller and supporting components, are overmolded and the complete device is housed in a 11.25mm x 15mm x 5.74mm BGA […]
Regulator module powers FPGAs, GPUs, ASICs
Analog Devices announces the Power by Linear LTM4646, a dual 10A or single 20A output, step-down µModule® point-of-load regulator from 5V or 12V input supply rails. The LTM4646 includes the inductors, MOSFETs, a DC/DC controller and supporting components, and is housed in an 11.25mm x 15mm x 5.01mm BGA package. Compared to the prior 2 x single […]
