The FAN7317MX is a multi-modulator controller ideal for applications that require multiple devices for power management, such as high efficiency and high current powering devices like voltage regulators, DC-DC converters and battery chargers. This integrated circuit has specific features such as wide input voltage range, pre-regulation and thermal shut-down control.

The FAN7317MX works by incorporating feedback loops within a device’s system. This allows the controller to measure and monitor properties such as inputs, outputs and temperatures. Defined by user set thresholds, the device then has the capability to adapt and adjust as required. In addition to global output voltage control and sensing, the FAN7317MX can provide additional features such as tracking, sequencing, peak current limit and others.

The FAN7317MX’s wide input voltage range and low quiescent current make it an optimal choice for applications that require both efficient and power-savvy power management. This IC’s range of adjustable voltage settings from 1.25V to 6.3V and its over-current limitation allow for superior protection of downstream components. As a result, the FAN7317MX can be used in a variety of applications across multiple industries, ranging from consumer electronics to medical equipment.

As a voltage regulator, the FAN7317MX can be used for systems that require both standard and low-voltage outputs. For example, it could allow the system to switch between dual outputs of 1.2V and 5V, while still maintaining power efficiency and high performance. While in step-up charging applications, this device’s integrated NDR provides smart current regulation and real-time monitoring of battery voltage and temperature. Ultimately, this allows for optimized charge rates to be set without the risk of overcharging or over temperature.

The FAN7317MX’s pre-regulation feature offers superior user-defined protection, allowing the device to immediately cut-off current supply in event of an over-temperature or over-current situation. As a result, the system can be protected from instability or damage that can occur from extreme conditions. Through the use of thermal sensing and thermal shut-down control, the FAN7317MX can also alert the user when output voltage or current become out of tolerance.

For applications where power cycling and sequencing are essential, the FAN7317MX provides peak current limit and enables multiple output power priorities. This feature also allows the user to create cost-efficient solutions by prioritizing output devices. In addition, the peak current limit is designed to prevent surge and over voltage of downstream components.

The FAN7317MX provides all these capabilities while offering excellent thermal, load and line regulation. Low dropout (LDO) and high side regulated linear post regulators can both use the FAN7317MX to provide the most current solutions for power management. For example, in LDO circuits the FAN7317MX provides pulse-width modulation (PWM) for better efficiency, and in linear post regulators it provides power efficiency, current accuracy and enhanced protection.

In summary, the FAN7317MX proves to be an invaluable asset to a wide array of power management applications. With its dynamic and versatile features and excellent regulation and protection capabilities, the FAN7317MX is the perfect choice for high-efficiency and high-current powering applications.
