Hi, with linear regulators the loss will always be: (V_in - v_out) * (I_out + I_circuit) letīs say your circuit consumes 2mA: then max loss is: (144V -12V) * (100mA +2mA) = 132V x 102mA = 13.5W For sure a heatsink can handle this. I recommend one with less than 2.5K/W ***** A switch mode regulator with 80% efficiency will generate abo
IPW90R1K FET... Pg 3 says max Qg is "tbd". Why is this?
Are you sure the chip can't work at 175C? Downhole applications seldom require the same service life as an industrial product's qualification assumes - like a few hundred hours max, at temp, vs a few thousand (at lesser temp). If you can find a ceramic package version of one you like, maybe do your own life testing and determine if you're just be
It is the same , that is until the Gain * f product (GBW) is reached. If OA has GBW of 1MHz then gain of 10 is 100kHZ BW. If usingg +/-10V supply (and has Rail to Rail saturating outputs) , then with a gain of 10, then the max. linear input range is <1V input max for either AC or DC or AC+DC
Actually I wouldn't like to use electromechanical relays as the one you suggested, since they are noisy and have limited switching capabilities (considering I'll be using a PWM). The approach I forgot to consider, and which might be the simplest of all, is to use a 250VAC/16A SSR controlled by a 3~32VDC/100mA.
Excellent analytical suggestions are given so far. When choosing a transistor , get one with single pulse power vs V ratings. Example of a 1W 60V NPN transistor. Notice 10ms @40V= 300mA max. . . You can extrapolate down to 10uS and obtain higher curren
GBW product of most Op Amps are low, so use unity gain. ESR of LED is low ( 15 Ohms ) so emitter resistor should be low ( 100 ) Then to make constant current sink use feedback from emitter or FET source instead of OA output. e.g. I would design this way THen the BW is limited only by the Op Amp's max BW at low gain.

What define the maximum speed rate is the technology employed in manufacturing such device at electronic level, therefore you must refer specifically to product specifications for take proper information.
This sensor has a 12-24V high side PNP output and you need a resitor divider from the output to ground to get a 5V max. signal. The diagram is shown here: . Enjoy your design work!
Hi all, I am planning to make an H-bridge for a DC motor. Here are the specs Supply voltage range - 12V to 30V max current ≈5A I am planning to use IRF530 and IRF530 and IRF9530 mosfets The gate driver I have planned to use is this. Is this and the two mosfets are good choices?

Whenever we are designing a product, we need to consider max power consumption at full load in power budget.
The datasheet for an opamp shows its frequency response and slew rate. The maximum gain of an OP07 opamp at DC to 1Hz is 1 million. At 1kHz its max gain is 1000. At 10kHz its max gain is 100 but the slew rate limits the output to only 8V p-p.
Hi! I have to design a circuit whose output should be the product of the two input voltages. The voltages can vary from -3 to +3 V and max. frequency is 10kHz. I am not supposed to use any analog multiplier IC. I thought of the log-antilog technique but it won't work as I have negative inputs. There was a circuit using MOSFETs in wikibooks but that
Read specification for that product, manufacturer described permited load per time. Example 1/4 max power continuos working for 10h. If try to use max power on longer time, maybe some problem will happen in malfunction, overheating,.... voltage drop depends from generator design.
... fT/10 is easy to achieve for a GBW of an amplifier. What is your idea of this fT ~~GBW relationship?? John: yeah, I think it's quite a good estimation, at least for an amp with max. 2 stages.
The transformer should not need a gap, so long as the max volt-time product applied to the primary is clamped to an appropriate limit, and the duty cycle is kept under %50. For the inductor that depends completely on the design details, but in general chokes with ferrite cores will require some gap.
Hi,I am using sim548z module and have made the circuit according to the hardware design guide that came along with the test it,i am using a bench power supply instead of VBAT with 5A max. To get the voltages for vrtc and gps_vcc,I have used following LDOs
Vout pp is limited by Vs pp. Hence Vout pp can only go up to Vs pp. Vout pp = Vin pp x max Gain Since Gain Bandwidth product, GBP = Gain x Bandwidth, we can say Bandwidth = GBP/Gain Why does an op amp bandwidth depend on vout pp ?
