2.7V-4.2V input to 3.3V – 0.6A output Buck-Boost Converter using LTC3440
https://www.electronics-lab.com/project/2-7v-4-2v-input-3-3v-output-buck-boost-converter/
This project shows a DC-DC buck boost circuit which can produce an output of 3.3V for an input of 2.7V to 4.2V , for example from a Li-on battery. The Circuit uses LTC3440 Buck boost IC which is a fixed frequency boost converter. To get high efficient results, inductor with high frequency core material should […]

Keeping up with Moore’s Law
https://www.electronics-lab.com/keeping-moores-law/
by Clemens Valens @ elektormagazine.com: There was a time that every extra storage byte crammed into a chip was greeted with cheers and applause but today only few people will get the champagne out when an extra gigabyte or so is announced. We have become so used to the ever growing capacity of memory chips […]
Load switch with self-resetting circuit breaker
https://www.electronics-lab.com/load-switch-self-resetting-circuit-breaker/
Anthony Smith has designed a simple load switch using two transistors and some resistors. The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load. The load current is limited by negative […]
LT8630 – 100V, 600 mA synchronous buck DC/DC betters 93% efficiency
https://www.electronics-lab.com/lt8630-100v-600-ma-synchronous-buck-dcdc-betters-93-efficiency/
LT8630 is a 600 mA, 100V input capable synchronous step-down switching regulator using synchronous rectification to deliver efficiency as high as 93% while Burst Mode operation keeps quiescent current under 7 µA in no-load standby conditions. by By Graham Prophet @ edn-europe.com: The device’s 3V to 100V input voltage range suits it for 48V automotive […]
Circuit implements photovoltaic-module simulator
https://www.electronics-lab.com/circuit-implements-photovoltaic-module-simulator/
José M Blanes and Ausiàs Garrigós writes: Electronics engineers often use photovoltaic-module simulators to test dc/dc-power converters, inverters, or MPPT (maximum-power-point-tracking)-control techniques. The use of these simulators lets you work in the laboratory with predefined photovoltaic conditions, thus avoiding the drawbacks of real photovoltaic modules. Various commercial simulators are available, but they are often expensive. […]
2.5A Bipolar Stepper Motor Driver using A3979
https://www.electronics-lab.com/2-5a-bipolar-stepper-motor-driver-using-a3979/
The tiny board designed using A3979 IC from ALLEGRO which is complete micro stepping driver with built in translator. The translator is the key to the easy implementation of the A3979. It allows the simple input of one pulse on the STEP pin to drive the motor one micro step, which can be either a […]
