Introduction:

MAX5039EUA-T is a power management integrated circuit (PMIC) from MaxLinear, belonging to the family of Specialized Power Management ICs (PMIC). It is designed for mobile, computer, and consumer products that require advanced power management functions, such as power sequencing and monitoring, in a compact size and energy efficient package.The MAX5039EUA-T provides a wide range of high efficiency and accurate power supply solutions. It includes a low dropout (LDO) linear regulator and a Boost/Buck (BB) DC/DC converter with ultra-wide input voltage range and configurable outputs, along with programmable voltage tracking and power sequencing. The device also includes programmable under-voltage lockouts (UVLO) and a RESET output pin with adjustable power-on reset threshold and delay notice.

Application Fields:

The MAX5039EUA-T has a wide range of application in today’s power management solutions. Its main applications are in mobile and handheld electronics, such as smartphones and tablets, as well as in wearables, industrial, and automotive applications. The MAX5039EUA-T is also suitable for laptop and notebook PCs, with its wide input voltage (6V to 28V) and configurable outputs up to 8V. Its integrated buck-boost and low drop-out regulators are perfect for powering video drivers, DDR SDRAM, and data processing devices such as SSDs, with excellent efficiency and accuracy.In addition, its high flexibility makes the MAX5039EUA-T ideal for accurate power monitoring and sequencing. It can be used to control the power up and power down sequence of consumer electronics such as TV, AC/DC adapters, modems and other consumer electronics.

Working Principle:

The basic working principle of the MAX5039EUA-T is centered around its multiple power management functions. The device contains a 2A boost or buck converter and a 2.2A linear regulator in a 6mmx6mm QFN package. The boost/buck converter is designed to operate from a wide input voltage range of 6-28V and supports output current up to 2A, adjustable from 3.3V to 8V through an external resistor. It also features comprehensive programmability for additional flexibility, including adjustable frequency and programmable soft-start and transition slew rate. The linear regulator provides an output voltage up to 2A, adjustable from 1.1V to 3.2V. It is protected with an adjustable UVLO, an over-current protection (OCP) and a thermal protection (TWR) to avoid thermal runaway conditions. The power sequencing features of the MAX5039EUA-T are also important. It can be set to any of 4 preset power-up or power-down sequences and the outputs can be tracked through the integrated voltage-tracking circuitry. This helps to ensure that the different power rail comes up safely and in the correct order and shuts down securely when power is removed.

Conclusion:

The MAX5039EUA-T is an advanced power management integrated circuit from MaxLinear, designed for use in a wide range of applications, from mobile, computer and consumer products, to industrial and automotive applications. It includes a low dropout (LDO) linear regulator and a Boost/Buck (BB) DC/DC converter with a wide input voltage range and configurable outputs, along with adjustable power sequencing, protection, tracking and monitoring features. With its versatile and wide range of features, the MAX5039EUA-T is ideal for today\'s power management solutions.
