Stephen Woodward’s DI, “Flip ON Flop OFF” does a wonderful job for DC voltages. I thought of extending this idea to much-needed AC voltages...
Push ON, push OFF for AC voltages
Toshiba launches second product in its SmartMCD series for automotive dual brushed DC motor applications
Toshiba Electronics Europe starts sample shipment for the TB9M001FTG, the second product in the innovative Smart Motor Control Driver series...
Simple PWM interface can program regulators for VOUT < VSENSE
I recently published a Design Idea showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface PWM to switching regulators”...
Take back half improves PWM integral linearity and settling time
PWM is a simple, cool, cheap, cheerful, and (therefore) popular DAC technology. Excellent differential nonlinearity (DNL) and monotonicity are virtually guaranteed by PWM...
Using generative AI to create hardware prototypes
A project in the UK and the Netherlands is using Large Language Models (LLMs) to create hardware designs with a technique it calls...
+5V powered charge pump battery charger
The circuit below will trickle charge a four cell pack of AA or AAA NiMH batteries...
Use a three-phase rectifier and voltage reducer for offline single-phase supplies
Some industrial applications require you to feed a low-power dc/dc converter from a three-phase source and possibly to deal with line-to-line voltages of 200 or 400 V rms. Further, the neutral terminal of the ac source may be unavailable for connection...
ADC clock polarity vs. start-up time
High speed analog-to-digital converters are by definition devices that sample an analog signal and, as such, must have sample clock inputs. Some system designers that utilize ADCs have observed a slower than expected startup from the time the sample clock is initially applied...
Designing 1 kW sine wave inverter circuit
An inverter provides power backup for mains-based appliances in the event of a power failure...
Renesas brings USB-C Rev. 2.4 support to new ultra-low-power RA2L2 microcontroller group
Renesas Electronics Corporation introduced the RA2L2 microcontroller group with ultra-low power consumption and the industry’s first support for the new UCB-C Revision 2.4 standard...
