LM53601LQDSXTQ1 is a DC/DC switching regulator from Texas Instruments. It is part of the Power Management ICs (PMICs) family, and it is particularly designed for Voltage Regulators, a specific category of DC/DC switching regulators. It is a single output synchronous Step-Down buck regulator that includes an adjustable output current limit and a diode emulation mode that make it particularly suitable for mobile and portable applications, such as in automotive or other battery powered systems.

This device operates in a step-down (buck) topology, using an internal high-side N-Channel MOSFET power switch, and it provides a regulated voltage over a wide VIN range. The output voltage is adjustable, with a minimum of 0.8V and a maximum of 4.5V. It is possible to set the constant current limit through direct connection of external resistors. This voltage regulator can reach a maximum of 5A output current, and it supports an operating frequency range of 1 to 2MHz.

LM53601LQDSXTQ1 has several features that make it suitable for a wide range of applications, such as:

• Spread spectrum modulation which reduces EMI
• Adjustable soft startup for current limit or other conditions
• Integrated output disconnect option
• Integrated over temperature protection
• LED current control mode operation
• Enable, reset, and power-good pins
• Automatic switch to Rich load mode for fast transient response
• Internal slew rate and over-voltage protection for increased robustness

The LM53601LQDSXTQ1’s step-down voltage regulator works by converting a higher input voltage (Vin) to a lower output voltage (Vout). It works in three distinct phases. During the first phase, an internal high-side N-Channel MOSFET is turned on, forcing current to travel through the inductor in a given direction. During the second phase, the internal MOSFET is turned off and the current produced from the first phase is stored into an output capacitor. In the final phase of the cycle, the current stored in the output capacitor is used to maintain the desired output voltage, while the inductor spins at a steady rate to produce the correct output current.

This device is a very useful and powerful option for applications needing a compact and efficient DC/DC voltage regulator, allowing for a wide input range, adjustable output current limit and LED current control. It is particularly suitable for applications where size and efficiency are prime requirements. Not to mention, its additional features are useful to ensure safety and accuracy, such as its integrated output disconnect, spread spectrum modulation and internal slew rate and over-voltage protection.
