The LX1663ACN is a feedforward, folding, low-dropout, high-efficiency linear voltage regulator designed to replace bulky switching regulators. This device can provide effortless management of medium amount of output power over a wide variety of systems, and its low-noise design has the flexibility to meet high-efficiency and small form factor requirements.

The LX1663ACN provides a maximum output power of 16V at 1.5A. It has excellent ripple rejection characteristics, and can handle up to 240 mV of output ripple with virtually no power losses. The device is designed to perform well even over the rating conditions of temperature, voltage, frequency, and phase margin.

The LX1663ACN can operate over an input voltage range of 5V to 24V. It includes protection for input overvoltage and thermal overload. The device also includes protection for undervoltage and overcurrent, making it robustly reliable for use in hostile environments. The LX1663ACN provides a highly efficient power source for a wide range of applications, from small, portable devices to large, high-performance equipment.

The working principle of LX1663ACN is simple but effective. The regulator uses a feedforward loop to track any changes in the output voltage. This feedforward loop is divided into two sections; the compensation loop and the control loop. The compensation loop operates in the frequency domain, while the control loop works in the time domain. The compensation loop determines the amount of voltage feedback received, while the control loop modifies the voltage feedback using a switch-mode technique.

The feedback control circuit inside the device helps to adjust the output voltage to a precise level. The LX1663ACN can be considered a hybrid device, combining the precision of a linear regulator and the efficiency of a switching regulator into a single component. The output voltage can be adjusted in two ways; by changing the voltage-feedback of the regulator or by changing the resistor divider connected to the voltage-feedback pin.

The LX1663ACN can be widely used in a variety of configurations and applications. It is ideal for applications such as battery-powered devices, wide-range DC/DC converters for office automation applications, portable instrumentation, handheld wireless and digital platforms, as well as motion controllers, power supplies and backlighting products.

The LX1663ACN is an excellent voltage regulator for systems requiring high efficiency and a small form factor. It has excellent ripple rejection and robust protection features, making it reliable in a wide variety of applications. All these features make it an ideal choice for designers who need an efficient but easy-to-implement voltage regulation solution.
