POL voltage regulator has five outputs for FPGAs, ASICs, multi-rail power systems
Infineon Technologies AG launches the IRPS5401, a five output Point of Load (POL) digital voltage regulator for FPGAs, ASICs, and other multi-rail power systems. The IRPS5401 has been developed as a fully integrated PMIC solution that replaces multiple regulators with a single device in a compact 7 mm x 7 mm 56 pin QFN package. […]
Synchronous step-down switcher delivers 4 A with 94% efficiency
The LT8650S is a dual 4A, 42V input synchronous step-down switching regulator. It’s unique Silent Switcher2 architecture uses four internal input capacitors as well as two internal BST and a single INTVCC capacitor to minimize the area of the hot loops. Combined with very well controlled switching edges and an internal construction using copper pillars […]
Step-down regulator delivers 2 A from tiny 6.25 x 4-mm BGA package
The LTM8063 from Analog Devices is a 40VIN, 2A µModule step-down regulator in a tiny 6.25mm x 4mm BGA package. According to the company, the package size is 75% smaller than the existing equivalent product. With two 0805 size capacitors and two 0603 size resistors, the solution is only 70mm². The Silent Switcher architecture minimizes EMI emissions, enabling the […]
Buck-boost regulator targets mobile platforms using reversible USB Type-C connectors
The ISL95338 buck-boost voltage regulator for tablets, ultrabooks, power banks, and other mobile devices using the reversible USB Type-C connector. Intersil’s new bidirectional voltage regulator accepts input power from a wide range of DC power sources — AC/DC power adapters, USB power delivery (PD3.0) ports, travel adapters, power banks — and converts it to a […]
Step-down regulator supports N+1 current sharing
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 […]
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. […]
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 […]
