The MAX17548EVKIT# is an evaluation board designed for voltage regulators and offline SMPS DC/DC and AC/DC applications. It provides a platform to evaluate the performance of the MAX17548, a complete dual-input buck DC/DC offline SMPS controller and the integrated MAX17744 offline AC/DC SMPS controller with automated adaptive switching between source types.

The MAX17548EVKIT# operates with an input voltage range of 4.2V to 24V from either a battery or wall adapter. It also supports a wide range of battery chemistries, including Li-ion and NiMH, as well as high efficiency burst-mode operation. The MAX17548EVKIT# is typically used in wireless charging systems, mobile phone systems, ultracapacitor backup systems, and other AC/DC or DC/DC applications.

The MAX17548EVKIT# provides a comprehensive set of features such as two-phase soft start, selectable frequency, phase spreading, dynamic loop control, and built-in safety features. In addition, the MAX17548EVKIT# supports a wide range of voltage ranges, including high voltage buck-boost conversion. The MAX17548EVKIT# also includes onboard diagnostic functions.

The working principle of the MAX17548EVKIT# is based on two primary functions: voltage regulation and automated switching between sources. To regulate the output voltage, the MAX17548EVKIT# utilizes its integrated MAX17548 offline SMPS controller, which implements a variable frequency Pulse Width Modulated (PWM) buck controller and a linear current regulator. The MAX17548 is capable of providing high efficiency, low voltage ripple, and fast transient response from input voltages ranging from 4.2V to 24V.

In addition, the MAX17548EVKIT# includes the MAX17744 offline AC/DC SMPS controller, which provides automatic switching between a battery source and a wall adapter supply. The MAX17744 features an adaptive switching algorithm that switches between sources based on the current battery and wall adapter levels. This adaptive algorithm saves power and reduces charge times by optimizing the source usage.

The MAX17548EVKIT# also includes several built-in safety features, such as overcurrent protection, reverse current protection, and short circuit protection. In addition, the MAX17548EVKIT# supports multiple operating modes, including low power, active, sleep, and standby. The MAX17548EVKIT# also offers a wide range of diagnostics, such as voltage monitoring, current monitoring, and thermal monitoring.

The MAX17548EVKIT# can be used in a wide range of DC/DC or AC/DC applications, from high voltage buck-boost conversion to wireless charging systems and mobile phone systems, due to its wide range of features and its high performance. The MAX17548EVKIT# also enables efficient power conversion and fast response time when used in offline SMPS DC/DC and AC/DC applications.
