LMR24220TLX/NOPB PMICs are mainly used in applications that require high efficiency and low noise at low Vin and Vout conditions, such as automotive and industrial applications, on-board DC-DC converters, notebooks, telecom infrastructure and consumer products. This device is particularly suited for demanding, high performance DC-DC step-down (buck) converting applications.

Working Principle

The LMR24220TLX/NOPB uses a synchronous buck architecture with voltage-mode control, allowing the device to operate with excellent dynamic response, high current ripple rejection and output noise suppression. This buck regulator has a built-in PFM/PWM mode switch, which can be independently activated via the synchronization pin. The device is also equipped with a low-dropout voltage regulator. Both the feedback voltage and the reference voltage are internally generated.

The device provides user control over several functions, such as the current limit, soft-start and adaptive frequency compensation. The current limit may be adjusted externally to allow the user to optimize their application for maximum efficiency or dropout voltage. The soft-start feature can be used to slowly charge an output capacitor for transient current limiting, Inrush current protection, and other sequencing applications.

At the core of this synchronous buck regulator is a stable, predictable, and fast PFM control loop, which ensures maximum efficiency and high transient response times. It also utilizes a built-in adaptive frequency compensation to optimize the transient response for a given set of components. The internal PFM circuit combines constant current control with pulse-width modulated (PWM) control, providing a very fast and efficient response in a wide range of input conditions.

Conclusion

The LMR24220TLX/NOPB is an ideal choice for applications where high efficiency, low noise and excellent load regulation are paramount. It features low dropout, its operating frequency can be synchronized externally, and it is designed with several control features to provide maximum flexibility to the user. It is available in a space-saving 8-pin ThinSOT package and comes with a low-noise voltage regulator.
