Analog Devices, Inc. is now offering the LTM4645, a 25A step-down regulator with the ability to current share multiple independent devices (N) where at least one LTM4645 is used as backup (+1) to ensure power availability if one device in this N+1 arrangement detects a fault and must be disconnected. For example, a 75A, 1V load […]

Isolated dc-dc converters feature ±1% regulation
Vicor Corporation announced the expansion of its family of isolated, regulated DC-DC converter modules (DCMs) in ChiP packages, with a range of ±1% voltage regulation devices. With power densities of up to 1,032 W/in3, the new series will offer engineers the option of directly driving loads that require tightly regulated output voltages. Vicor’s current family […]
Step-down 5-V regulator handles noisy 40-V inputs
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTM8065, a µModule (power module) step-down regulator with up to 40V input voltage (42V abs max), which can safely operate from unregulated or fluctuating 12V to 36V input supplies in noisy environments such as industrial robotics, test and measurement, medical, factory automation and avionics systems. […]

DC-DC power IC converts 48 V to extremely low voltage
The HS200 is a dc-dc power IC that offers greater than 97% efficiency at 2.6 W and greater than 90% efficiency at 15 W. With no load, the HS200 consumes only 0.5 mW. Power can be pulled from any of its three outputs simultaneously up to 15 W. Efficiency is nearly flat from full load […]
SLDM Tunable LoopTM Non-Isolated DC-DC Converter
Bel Power Solutions announces the new SLDM Tunable LoopTM SLDM-06D1Ax and SLDM-12D1Ax modules, which are ultra-low profile, non-isolated DC-DC converters that deliver up to 6A and 12A with maximum flexibility of being mounted on the top side or bottom side of the host PCB. The SLDM modules fit into the smallest, tightest spaces (only 2.8mm […]
ZVS buck regulators provide 20 A
Vicor today announced that it has extended its Cool-Power 48V ZVS 20A buck regulator portfolio by releasing the PI3523-00-LGIZ (PI3523). The PI352x family offers 20A solutions complementing the previously released 10A 48VIN PI354x family, enabling scalable power options for 48V direct to point-of-load (PoL) applications. The PI3523 is a 48VIN, 3.3VOUT nominal Buck Regulator capable […]
DC-DC converters deliver up to 6A and 12A in top- or bottom-side mount
Bel Power Solutions announces the new SLDM Tunable Loop SLDM-06D1Ax and SLDM-12D1Ax modules, which are ultra-low profile, non-isolated DC-DC converters that deliver up to 6A and 12A with maximum flexibility of being mounted on the top side or bottom side of the host PCB. The SLDM modules fit into the smallest, tightest spaces (only 2.8mm high, […]
40-A synchronous DC/DC buck converter with advanced-current-mode control topology said to be an industry first
Texas Instruments introduced the industry’s first 16-V input, 40-A synchronous DC/DC buck converter with an internally compensated advanced-current-mode (ACM) control topology supporting frequency synchronization. TI’s TPS543C20SWIFT converter provides enhanced efficiency by integrating its latest generation of low resistance high- and low-side MOSFETs into a thermally efficient small-footprint package. Designers can stack two converters side by side […]
Rugged 15-W dc/dc converter sits in 1×1-in. footprint
TRACO POWER has announced the release of their THN 15WIR Family of ruggedized DC/DC converters designed for harsh environments in a miniature 1 x 1 x 0.40” footprint. The converters offer increased resistance against electromagnetic interference, shock/vibration and thermal shock with EN 50155 and EN 61373 compliance making them ideal for railway, transportation, and harsh […]
