MAX17548ATJ+T

The MAX17548ATJ+T is a high-efficiency, non-synchronous, step-down DC-DC regulator. It is designed for automotive applications, such as air conditioning, headlights, navigation systems, communication, and entertainment systems. The device can operate from an input voltage of 4.5 V to 60 V and deliver up to 6 A of output current. It also features high efficiency, an adjustable voltage output, constant-frequency current mode operation, low on-resistance, integrated linear controller and low quiescent current.

The MAX17548ATJ+T consists of one power stage and one control stage. The power stage includes an internal power switch, an integrated PHEMT switch, and an internal high-side PMOS switch to provide a complete step down DC-DC regulator. The PHEMT switch is used to control the output voltage. It is designed to provide efficient step-down conversions from high input voltages, while maintaining very low on-resistance to reduce power consumption and minimize the external components count.

The control stage is composed of a linear controller and an internal high-side PMOS switch. The linear controller modulates an internal clock with reference to an external compensation pin to provide an adjustable voltage output. The P-channel MOSFET switch is used to reduce the quiescent current of the regulator, resulting in a longer battery life and lower power consumption.

The MAX17548ATJ+T is capable of delivering up to 6A of output current. The output voltage can be adjusted from 0.6V to 5.5V, with a minimum output voltage range from 0.8V to 5.5V. The device also features low dropout voltage, fast loop response, low output voltage ripple, and a wide input voltage range. It also has a built-in thermal shutdown protection, over current protection and short-circuit protection to protect the device from damage in extreme conditions.

The MAX17548ATJ+T is a very efficient DC-DC regulator ideal for automotive applications requiring step down conversions from high input voltages. It features high efficiency, adjustable output voltage, low on-resistance, low quiescent current, and fast loop response. Its built-in protections make it safe to use in extreme conditions while its wide input voltage range makes it compatible with a variety of applications.
