Part Number: LM22678-Q1 I built a power supply following the schematic generated by webench, but it draws a very high current from source and blows up almost instantaneously when switched on. It must be something very obvious, but I can't see it at the…
Other Parts Discussed in Thread: LM22678-Q1 Dear, Sir.
My customer has designed the power supply applying LM22678-Q1.
LM22678-Q1 was broken due to Output short to GND wihin quite short time
(It is depended on miss-operation by the customer).
Vin =…
Other Parts Discussed in Thread: LM46000 , LM43600 , LM22678-Q1 Hi,
I need a 12VDC to 5VDC 1 Ampere step down converter with surge protection.
Kindly advise if there are devices which fulfil this requirement.

Other Parts Discussed in Thread: LM22678-Q1 , LM22678 Hello,
I've started a power design using TI's WEBBENCH. The resulting design utilizes a LM22678-Q1 (-5V). The output plots show under 3mV of ripple, which is acceptable. However, I don't know…
Hi Gaston,
Each vehicle manufacturer has its load dump and cold crank transient voltage specification. It is necessary to provide an overvoltage protection circuit to prevent the LM22678 from exposing to transient voltage above 42V max. and a blocking…
