Providing 96–135W of continuous output power, the PUP121 and PUP136 series of AC/DC switching power supplies have been introduced by Power Sources Unlimited. Enclosed in a 1″ case with an IEC320/C14 or EC320/C6 inlet for world-wide use, the devices meet efficiency Level VI as well as Energy Star EPS2.0 / ErP Lot7.
MMIC power amp eliminates need for RF switches
Analog Devices has introduced the HMC1127 and HMC1126 MMIC distributed power amplifiers. Covering the frequency range of 2-50GHz, these power amplifier die simplify system design and improve performance by eliminating the need for RF switches between frequency bands. Each amplifier incorporates I/Os that are internally matched to 50Ω, facilitating easy integration into multi-chip modules.
MOSFETs save space in DC end applications
Infineon has launched a family of StrongIRFET MOSFETs for DC powered circuits including battery powered circuits, brushed and BDLC motor drives. The MOSFETs offer efficiency for end applications such as power and gardening tools, light EVs, UAVs and e-bikes that demand a high level of energy efficiency but are restricted in available space. This is made possible by the compact Medium Can DirectFET housing featuring a...
The effect of internal phase shift on power measurement
The measurement of electrical power depends on voltage, current and time. All three contribute to the total uncertainty of the measurement. Ben Kemink, Yokogawa, shows how effects can be minimised by careful power-meter design.
Designing the next smart and lower-power applications
Dung Dang, Texas Instruments explains why Texas Instruments introduced the MSP432 MCU to address the power-saving issues while raising the bar for high performance on ultra-low-power MCUs.
