Fully integrated SVID and PVID-enabled voltage regulator brings high efficiency in a small package
An Integrated Point-of-Load (IPOL) family combines ease-of-use with high power density. It is said to be the industry’s first fully integrated regulator offering PMBUS, SVID and PVID functions for powering Intel CPU POL rails, chip-sets and ASIC/FPGA. With 50% space saving compared to alternative external power solutions, this is said to be the smallest solution […]
ZVS buck regulator puts out 20 A at 24 V
The new Cool-Power ZVS buck, PI3325-00-LGIZ, represents the highest current output ZVS buck to date for 24/28-V applications, providing a regulated 5-V output at up to 20 A. Packaged within a 10x14x2.5-mm LGA SiP package, the PI3325-00-LGIZ addresses the continued need for high power density across a growing spectrum of applications. It also offers pin-for-pin […]
Auto-grade regulator transistors tolerate 60-V battery transients
The ZXTR2105FQ, ZXTR2108FQ () and ZXTR2112FQ regulator transistors announced by Diodes Incorporated are qualified to AEC-Q101 standards for high reliability and are product part approval process (PPAP)-capable. Designed to deliver 5V, 8V, or 12V regulated outputs from nominal battery supplies of 12V or 24V, these regulator transistors are well-suited for powering vehicle electronics. These devices can […]
Compact LED drivers put out 24 W with 20 W/in.3 power density
Seoul Semiconductor has developed an ultra-compact LED driver series with a power density 5X higher than conventional LED drivers. Based on Seoul Semiconductor’s patented Acrich technology, the MicroDriver Series delivers more than 24W of output power with a power density of 20W/cubic inch cubic inch, compared to existing drivers at 3-5W/cubic inch. Measuring just 1.5” […]

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 […]
