New 1A Switching Regulator K78-1000R3 Series
MORNSUN extends its portfolio of non-isolated switching regulator DC/DC Converter with a new series: K78-1000R3. As K78-500R3(500mA output) has enjoyed great popularity from the market, K78-1000R3(1A output) series is designed to meet wider output power range requirement of customers’ application. Same as K78-500R3, K78-1000R3 series are in SIP package with high efficiency up to 96%, […]
Synchronous buck regulators step-down 5 and 3.3-V primary rails to POL inputs
Intersil Corporation has announced a family of monolithic synchronous buck regulators that step-down 5V and 3.3V primary rails to point-of-load (POL) inputs as low as 0.6V for GPUs, FPGAs, DSPs and SOCs. The highly efficient ISL78233, ISL78234 and ISL78235 deliver 3A, 4A and 5A, respectively, of continuous output current to infotainment head units and advanced […]
Wide range DC-DC converters provide negative outputs
TDK Corporation announces the introduction of the 75W rated TDK-Lambda i6AN series of negative output non-isolated DC-DC converters. Capable of operating from an input voltage of +9V to +40V, the step-down converter delivers an output voltage that can be adjustable from -3.3V to -30V and output currents of up to 8A. The series is designed […]

New DC/DC converter for PV power system handles up to 1500 VDC
A trend of photovoltaic industry is that 1500VDC system will be in place of nowadays standard 1000VDC system. Higher-voltage systems enable longer strings, which allow for fewer combiner boxes, less wiring and trenching, and therefore less labor. Input voltage from 1000VDC to 1500VDC allows longer strings used in the PV system. Most of the PV […]
New 1-2W G/H series medical DC/DC converter
MORNSUN recently released new 1W/2W DC/DC Converter G/ H series targeting medical, which meet medical design standard EN60601-1 and ANSI/AAMI ES60601-1 3rd Edition (1xMOPP/2xMOOP). Both creepage and clearance of the module’s transformer are 5mm, and 5.5mm for PCB. And the isolation voltage of the module is as high as 4200VAC (6000VDC), which is 40% higher […]
15-A, 20-A POL Regulators target servers with better energy efficiency
Exar Corporation, a supplier of analog mixed-signal products serving the industrial, high-end consumer and infrastructure markets, introduced the XR76116 and XR76120, 15A and 20A point-of-load (POL) step-down buck switching regulators using the latest generation of Exar’s patented emulated current mode constant on-time (COT) control. This control loop provides the fast transient response required in demanding […]
