Abstract: This applicaTIon note shows a reference design using the MAX15026 low-cost, high-efficiency synchronous buck converter in an auxiliary power supply for LCD TVs or set-top boxes. This reference design generates a 5V, 5A power supply from a wide, 6.5V to 24V input …
Abstract: Maxim manufactures several delay lines. This applicaTIon note compares each programmable delay line and non-programmable delay line to help customers choose the appropriate device for their applicaTIon. Since many of the features of these devices cannot easily be…
Abstract: When a white LED is used as a backlight for a display or other lighting equipment, it needs to be driven with a constant current. The main reasons are: To avoid the drive current exceeding the maximum rating and affecting its reliability. Obtain the expected brig…
Abstract: Analog switches are commonly used in audio systems to switch low-level inputs or adjust audio filter characterisTIcs. SelecTIng the proper analog switch can help opTImize the total harmonic distorTIon (THD) of a system within the designer's cost budget.

Abstract: This applicaTIon note describes how to erase / write the program and data flash in the MAXQ7665 microcontrollers (µC) using the built-in uTIlity ROM. This informaTIon applies only to the MAXQ7665 flash-based microcontrollers (µC) with sector-erasable ( SE) …
Abstract: The MAX9217 / MAX9218 serializer and deserializer chipset implement video data transmission through a pair of twisted pair LVDS links, and are widely used in automotive and industrial applications. Each frame of the video signal always has blanking periods, and t…
Abstract: A DS4402 or DS4404 adjustable-current DAC is used to adjust the margin of a DC-DC converter's output voltage. This arTIcle describes how to properly select the resistor values ​​in a DC-DC converter's feedback divider network when a DS4402 o…
Abstract: In ISM 300MHz to 450MHz band short-wave communications, low-cost ASK and / or FSK transmitters and transceivers are its core devices. Typical applications of these short-range communication devices (SRD) are wireless remote access control systems (RKE), tire pres…
Abstract: Reducing electromagnetic interference (EMI) is an important factor that electronic system designers need to consider. Spread-spectrum clock (CLK) provides an effective way to reduce EMI. This article gives the definition of spread spectrum CLK and a simple formul…
