Analysis of buck converter efficiency
https://www.electronics-lab.com/analysis-buck-converter-efficiency/
Tech note from Richtek on buck converter profiling. Link here The synchronous buck circuit is wildly used to provide non-isolated power for low voltage and high current supply to system chip. To realize the power loss of synchronous buck converter and to improve efficiency is important for power designer. The application note introduces the analysis […]
90V to 10V @ 500mA High Voltage DC-DC buck converter
https://www.electronics-lab.com/project/90v-10v-500ma-high-voltage-dc-dc-buck-converter/
This is a versatile tiny module that provides 10V/500mA from 90V DC input. It is a high voltage input DC-DC buck converter, based on LM5017 IC, which is a 100-V, 600-mA synchronous step-down regulator with integrated high side and low side MOSFETs. The constant on-time (COT) control scheme employed in the LM5017 requires no loop […]

Mini ATtiny3217 development breakout board in DIL24
https://www.electronics-lab.com/mini-attiny3217-development-breakout-board-dil24/
Albert van Dalen writes on avdweb about making a tiny development board in a DIL24 format containing a Microchip/Atmel ATtiny3217 microcontroller. The Dily3217 is an Arduino compatible development board of 30x10mm, easy to integrate since it has a breadboard-friendly narrow DIL24 package. It is powered by the new ATtiny3217 and it has 21 I/O lines. […]
NVE Introduces Smart I²C TMR Angle Sensor
https://www.electronics-lab.com/nve-introduces-smart-i%c2%b2c-tmr-angle-sensor/
NVE Corporation expanded its line of angle sensors with the new ASR012-10E Smart I²C TMR Angle Sensor. The ASR012 is based on the same TMR sensor element and digital processing core as the ASR002, but with an Inter-Integrated Circuit (I²C) rather than a Serial Peripheral Interface (SPI). The new part also provides a pulse-width modulated […]
