The MAX6499 comprises undervoltage and overvoltage comparators for window detection. WHen the monitored voltage is within selected “window”, GATE is enhances and the n-channel MOSFET is on. GATE falls to OUTFB when the monitored voltage falls below the lower limit (V triplow) or exceeds the upper limit (Vtriphigh) of the window, turning off the MOSFET. The MAX6499 enabling the DC-DC […]

To protect downstream circuits from overvoltage conditions that show up during load-dump events or transients, we can use the MAX6495–MAX6499/MAX6397/MAX6398 overvoltage protection (OVP) devices. Here’s the circuit diagram: This devices work by controlling an n-channel MOSFET wired in series with the power rail. The gate pulls low and the MOSFET shuts off, disconnecting the power rail when the voltage surpasses […]

We can use boost converter such as TPS61160/1 with a 40V rated integrated switch FET to drive up to 10 LEDs in series. We can use it to reduce output ripple, improve conversion efficiency, and allows for the use of small external component. The external sensor resistor Rset is set on the default white LED current with feedback voltage is […]
