    RT8015B RT8015BGQW RT8015BGSP Datasheet

    The RT8015B RT8015BGQW RT8015BGSP are high efficiency synchronous, step down DC/DC converter. Its input voltage range is from 2.6V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 3A of output current.

    The internal synchronous low on resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is set by an external resistor. The 100% duty cycle provides low dropout operation extending battery life in portable systems. Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors.

    The RT8015B is operated in forced continuous PWM Mode which minimizes ripple voltage and reduces the noise and RF interference.

    The 100% duty cycle in Low Dropout Operation further maximize battery life.

    The RT8015B RT8015BGQW RT8015BGSP are available in the WDFN-10L 3x3 and SOP-8 (Exposed Pad) packages.

      Galax 3090 bad duty cycle on mem phase
      by pedrolopesbe
      I got this 3090 wich I own, same board as the common 388_50 boardview.
      I'm new to SMD work, and in a moment of stress trying to solder a 0402 filter cap that I've knocked out I've made a big solder mess in the "U42" drmos.
      As past is past, after getting a pre heater now I succesfully unsoldered the chip but I'm having problems soldering it back again.
      At the last time I've worked on it, I had to reflow it as it was not giving any out signal, measuring using the Hz function in my multimeter.
      Now I get a reading of something like 1.7kz while other phases 3.09khz...

      MT3608 Step-Up Converter IC Datasheet
      by Document Archive
      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...

      Asus Z97-a power cycle, no boot no cpu voltage
      by meraklinetx
      Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...

      AOZ2261NQI-11 Datasheet
      by Document Archive
      General Description

      The AOZ2261NQI-11 is a high-efficiency, easy-to-use DC/DC synchronous buck regulator that operates up to 28V. The device is capable of supplying 8A of continuous output current with an output voltage adjustable down to 0.6V ±1%.

      A proprietary constant on-time PWM control with input feed-forward results in ultra-fast transient response while maintaining relatively constant switching frequency over the entire input voltage range. The on time can be externally programmed up to 2.6µs.

      The device features multiple protection functions such...

      Vizio TV M50-C1 reboot cycle and static on screen
      by spice_disc
      I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

      The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...
