The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height.
Internal soft-start results in small inrush current and extends battery life.
The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. The MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MT3608 is available...10-07-2024, 05:02 AM -
Hi folks.
Any help with identifying this IC? Should be some DC/DC step down converter. 'ACF G45' ... I thought, it is Monolithic Power Systems ( based on this topic --> https://www.badcaps.net/forum/troubl...and-datasheets ), but can't find this marking there.โ Will be thankful for any hint. Thanks in advance.... -
Hello everybody,
I need to replace a shorted SOT23-5 step down converter in a consumer audio device marking E16q9. What I found out from the board layout and measurements:
Vin: 5,0V
Vout: 3,3V (connecting to all 3V3 inputs of a N32905U3DN)
Pin1: ? (perhaps enable)
Pin2: GND
Pin3: Vout - connected to 3ยต3 coil
Pin4: Vin
Pin5: Feedback, voltage divider, two resistors connect Vout-Pin5-GND, 680k+133k
I searched many datasheets, but no one seemed to match according the surrounding components.

Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. ๐
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

To test I plug in a 12v source and try by plugging a multimeter on the output and turning on the blue trim potentiometer it's fix at 12v however I turn it up or down what could be wrong ?...
