Max1734euk18+t Application Field And Working Principle

Max1734euk18+T is a DC DC switching regulator that belongs to a series of PMIC (Power Management ICs). It is a programmable voltage regulator and combines a low-dropout linear regulator with a low-loss step-up DC/DC converter. It is designed to provide stable, quiet and accurate output voltage across a wide range of input and output voltages and currents.The Max1734euk18+T is designed to be used in a broad range of portable and stationary applications such as cell phones, PDAs, MP3 players, digital cameras, portable medical devices, laptop computers, network and storage devices, tablets, and set-top boxes. The chip can operate from a 1.8 V input to a 5.5 V output, making it suitable for portable applications.The Max1734euk18+T features a switching frequency variable from 250 kHz to 2 MHz, enabling soft-start and low noise operation even at high switching frequencies. The output voltage is programmable and can be adjusted in small increments over a range of 0.5 V to VCC (5.5 V). The controller supports a wide range of output currents, up to 5 A. It also offers a low quiescent current, typically 0.9 μA, when the output is disabled, saving power in battery applications.The Max1734euk18+T operates in either a hysteretic or voltage mode. In hysteretic mode, the device adjusts the output voltage using a voltage-by-voltage feedback loop, which results in low variation over the line and load. In voltage-mode operation, the device maintains the output at a desired voltage by monitoring and controlling the output voltage. The input voltage tolerance is also improved because the output voltage is controlled by the input voltage.The Max1734euk18+T includes a power-saving feature which reduces the quiescent current when the load is minimal. It also includes built-in diagnostics such as thermal shutdown and undervoltage lockout. The Max1734euk18+T is available in a space-saving 4 x 4-mm WLP-10 package.The Max1734euk18+T is a user-programmable step-up switching regulator with low noise, low dropout and low quiescent current. It can be used in a wide range of applications, including portable and stationary products, providing a stable and accurate output voltage across a wide range of input and output voltages and currents. Its adjustable frequency and programmable output voltage range allows for customization and efficient operation. With its power saving features, built-in diagnostics, and small size, the Max1734euk18+T is well suited for the demands of today\'s portable applications.
