The LP3917RLX-S/NOPB is a high performance Power Management Integrated Circuit (PMIC) used for a wide range of applications that require superior power conversion and system control. It is part of a family of distinct and robust power management ICs (PMICs) offered by National Semiconductor Corporation. The PMICs are typically used in the industrial and automotive markets, as well as the consumer and computing markets.The LP3917RLX-S/NOPB is designed to handle power demands from low voltage sources such as power from batteries. The PMIC is capable of unidirectional and bidirectional regulation for demanding current and power supply control requirements. This feature makes the LP3917RLX-S/NOPB suitable for both low voltage single-cell and multi-cell batteries, or as a complete system power supply.The LP3917RLX-S/NOPB features a precision low dropout linear regulator which is capable of supplying up to 2A of continuous output current over an extended temperature range. It also features a voltage reference with an accuracy of ±1%. This makes it an ideal power management solution for precision systems. The LP3917RLX-S/NOPB also includes a digital power controller that supports up to 2x2A of voltage and current regulation. The digital power controller is customized for each application to meet the specific needs of the system for complex power conversion requirements.The LP3917RLX-S/NOPB also features two integrated on/off-time configurable PWM (Pulse Width Modulation) controllers. These can be used to drive an H-bridge or other type of power stage to provide an adjustable voltage or current for a variety of applications. The PWM controllers are capable of operating in a variety of frequency ranges and at duty cycles up to 100%. The two independent PWM controllers can be used to drive two separate loads from the same input, or they can be synchronized to provide a single synchronous drive.The on-board I2C/SMBus Controller is used to communicate to the host microcontroller or processor. The I2C/SMBus Controller supports multiple slave devices, allowing for simultaneous and efficient communication between the power management IC and other components in the system, such as analog-to-digital converters and digital-to-analog converters.The LP3917RLX-S/NOPB provides a wide range of features, making it suitable for a variety of applications. It can be used in industrial and automotive environments, as well as consumer and computing applications. The integrated PWM controllers, I2C/SMBus Controller, and precision low dropout linear regulator help to make the LP3917RLX-S/NOPB a robust and reliable choice for power management.
