The junction temperature is: No additional import charges on delivery.

I’ll also keep looking for better capacitors, maybe another option is desoldering the caps from broken motherboards? Delivery times may vary, especially during peak periods and will depend on when your payment clears – opens in a new window or tab. The output voltage is adjusted by means of the resistors R1 and R2 according to the following equation: For full datasheets, application notes and selection guides, see http: For the most current data, consult LinFinity ‘s web3.

Part Number Series: LX8 Series

It is important to give careful consideration to all sources of thermal resistance from junction to ambient. All voltages are with respect to Ground. The selected heat sink must.


The LX is designed for low cost, not optimal transient response, making it ideal for this application. Note that the case of all devices in this series is electrically connected to the output. Advanced fault protection features include lx8348 over-voltage protection OVP and hiccup-mode overcurrent protection. Originally Posted by rattlesnake Yes! Thermal resistance from the mounting.


Switchers linfiniyt generally more expensive than linear regulators at lower currents, but the benefits of higher efficiency make switching regulators the solution of choice for higher power levels.

To ensure good transient response from the power supply.

K5 is a registered trademark of AMD. Load regulation will be limited by the resistance of the wire.

AN-6: Power Solution for Flexible Motherboards

First, find the maximum allowable thermal resistance of the heat sink: My assumption from this description is you tested the motherboard with all the caps installed, correct? Sign in for checkout Check out as guest.

However, there are several limitations of linear regulators as power levels increase. Table 1 – Available Options.

See other items More B ecause the shooting time, all of our product lot numbers are the latest batch. Long Term Stability Note 3. Lintinity was also reading about capacitors: This document may not be modified in any way without the express written consent of LinFinity. I don’t think the BIOS is compromised, but you never know, it could be!


What is linfnity doing to fix this motherboard or at least to finish the diagnose? So if this is right, the correct count of the aluminum electrolytic capacitors is: For continuous normal load conditions. It is important to keep the connection between the regulator output pin and the load as short as possible, and to use wide traces or heavy-gauge wire.
