Bang-bang photovoltaic regulator needs no magnetics
01.14.2018 · Circuits
Photovoltaic systems commonly include a means of energy storage – batteries or supercaps – to provide electricity to the load when sunlight is not available or during power transients. However, when feasible, storage-free systems are an environmentally-friendlier alternative with higher MTBF...
AKM releases a Motor Driver that is Capable of Running on a Single 18V Power Supply, the AP1010, Suitable for Home Electronics
01.14.2018 · News
Asahi Kasei Microdevices Corporation, has developed a motor driver, the AP1010AEN, capable of operation with a single 18 V power supply. The AP1010AEN is ideal for 12 V systems such as home equipment, (e.g. opening/closing water heater valves), and white goods household appliances, (e.g. refrigerators and ice machines)...
Simple Transient-Response Measurement Determines Power-Supply Bandwidth
01.11.2018 · Articles
It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response – no good reference exists that defines this in simple terms. It seems like a straightforward problem, which should have a simple solution. The higher the bandwidth, the faster the loop responds, and with less voltage deviation...

Use an op amp as a set/reset flip-flop
01.10.2018 · Circuits
You can make a set/reset flip-flop from two NAND or NOR gates or use readily available set/reset flip-flop ICs, such as the 74HC279 quad-set/reset latch. The drawback of these methods is that they require a large amount of space to form the flip-flop...
New photodiode generation: revised package concept makes it easier for the customer
01.10.2018 · News
Osram Opto Semiconductors presents the world’s first SMT package for large-area photodiode chips which complies with the strict demands of the automotive industry and is even approved up to an operating temperature of 125 °C. The new SFH 2200 A01 and SFH 2200 FA A01 photodiodes meet the requirements for AEC-Q101-C qualification and are ideally suited for use in rain sensors...
A Low Power, Low Cost, Differential Input to a Single-Ended Output Amplifier
01.09.2018 · Circuits
In many applications, there are requirements of low power, high performance differential amplifiers to convert small differential signals to a readable ground referenced output signal. Input voltages at two inputs usually share a large common-mode voltage. The differential amplifier rejects the common-mode voltage and the remaining voltage is amplified and presented on the amplifier output as single-ended voltage...
