MAX17139ETL+T

The MAX17139ETL+T is a synchronous step-down voltage regulator circuit with a precise 1.5 A operating current and a wide input voltage range from 4.5 V to 36 V. The circuit provides high-precision, adjustable output voltage regulation in a high speed dc power-conversion process. It is used in applications such as embedded systems, telecom, power supplies, solar energy, automotive electronics, mobile computing, and embedded instrumentation.

The MAX17139ETL+T is available in a variety of packages, including surface-mount and through-hole packages. The circuit features an output voltage accuracy of ±1 % over line, load, and temperature, and is capable of supplying up to 1.5 A output current with efficiency up to 95 %. In addition, the extended operating range of 4.5 V to 36 V allows the regulator to be used in a wide variety of applications.

The circuit provides Output Discharge (OD) feature to reduce output ripple caused by load transients. The OD circuit allows the voltage regulator to continue supporting an output voltage of up to 0.5 V below the set point of the regulator until the load is removed. It helps to minimize the output voltage ripple and reduce the total output power dissipation of the device.

The MAX17139ETL+T operates in a PFM (Pulse Frequency Modulation) mode at light loads to reduce power dissipation and EMI generation. It can achieve high-efficiency levels over a wide range of operating conditions and can be used in a wide variety of applications, including DC-DC converter designs. The IC also supports a soft-start feature to reduce the inrush current at turn-on and provide better system protection.

The MAX17139ETL+T includes features such as over-voltage, over-current and thermal protection to prevent damage to the device in the case of an abnormal condition. The current-limit protection (CLP) circuitry monitors the output current and triggers a shutdown to prevent the device from being damaged due to an over-current or short-circuit condition. The CLP feature eliminates the need for an external current sense resistor and helps in achieving a fast response to transient over-current conditions.

The MAX17139ETL+T circuit is ideal for applications that require precise, adjustable output voltage regulation in a high-efficiency dc power-conversion process. It can be used in a wide variety of applications such as embedded systems, telecom, power supplies, solar energy, automotive electronics, mobile computing, and embedded instrumentation.
