PMIC (Power Management ICs) are a type of integrated circuit that are used to manage the power consumption of electronic devices. They are typically used in mobile electronics and in other portable, battery-powered electronics. LM27341SD/NOPB is a PMIC, belonging to the Voltage Regulators category and more specifically to the DC DC Switching Regulators sub-category. It is manufactured by Texas Instruments and its purpose is to provide efficient and reliable voltage regulation.

The LM27341SD/NOPB is a synchronous step-down DC/DC switching regulator with integrated power MOSFETs. It is offered in a small form factor, SOT-23-6, that is perfect for space constrained applications. It is operated from a +3.3 V to +28 V input and can generate an adjustable output voltage down to 0.8 V. The device uses a peak current mode control scheme for high efficiency, fast transient response and lows output ripple. It includes built-in protection features such as cycle-by-cycle current limiting, thermal shutdown and overvoltage protection. It can operate from 1.5 V to 5.5 V, while switching up to +1.25 A of output current. It provides a high efficiency, programmable frequency range of 250 kHz to 3 MHz.

In addition, the LM27341SD/NOPB is designed to meet the toughest demands of a modern high performance battery-based system by supporting an input voltage range of up to 28 V, making it suitable for many applications, such as power supplies, automotive, communications and industrial systems. Its synchronous rectification consigns current flow only when the output is actively driven, providing very low power dissipation and very high efficiency.

The LM27341SD/NOPB also features a low 0.6 V dropout voltage at 1.25 A with a programmable frequency range of 0.25 to 3.0 MHz. It features two wide range PWM/PFM modes, an internal soft-start, an internal compensation loop and a, power-good indicator. Furthermore, the LM27341SD/NOPB includes an Maximum Duty Cycle (MDC) pin for optimal peak current control in PFM mode.

The LM27341SD/NOPB is designed to operate with a wide input voltage range, and its efficiency is very high with its 1.25 A output current. The integrated power MOSFET, protection features and low dropout voltage provide reliable over-temperature and current-limiting protection. Also, the device is available in a small package, making it ideal for space constrained applications. Overall, the LM27341SD/NOPB is a versatile and reliable DC/DC switching regulator that provides efficient, reliable voltage regulation and can be used in a wide range of applications.
