The L9466N is a special purpose voltage regulator typically used in power management systems. It was developed to provide high-efficiency power and logic sequencing for microprocessors and digital logic circuits. It is a single-package power management IC designed for cost-sensitive and reliable solutions.

The L9466N is a small, single-package device that combines voltage management, protection, power sequencing, and power distribution. It contains a voltage regulator, an integrated configuration and readback logic, and up to 8 logic-controlled outputs. It also includes self-protection features such as input overvoltage protection, output overvoltage protection, overcurrent protection, and thermal protection. The device requires a single 3.3V or 5V supply voltage and provides up to 8 programmable voltage outputs with an adjustable voltage range of 0.7V to 5.5V. The on-chip control logic enables voltage-level translation and timing, sequence, and configuration/bi-directional I/O capabilities.

The L9466N is designed to be configurable by the user, and offers several features to simplify the power management design. The integrated configuration memory allows the user to define and store the on-chip power supply configuration. It also features an integrated EEPROM so the user can store up to 256 bytes of data for non-volatile storage. This can be used to store custom settings, such as factory calibration data, thermal coefficients etc.

The L9466N is well suited for a variety of applications that require a wide input-to-output range, high efficiency and flexibility. It can be used in a variety of applications including notebook and desktop PCs, PDAs, cell phones, routers, and personal digital assistants. It also has a wide range of input voltages, ranging from 3.3V to 28V, making it suitable for many applications.

The L9466N is based on a buck regulator topology with a synchronous rectification scheme. It uses a single control loop to regulate the output voltage. The output voltage is sampled through a resistor divider, and is compared to an internal reference voltage. An error amplifier then adjusts the voltage until the output voltage is within a predetermined range. The error amplifier drives a high-side P-channel MOSFET and low-side N-channel MOSFET, which then set the operating frequency and transition times of the buck regulator.

The L9466N provides a complete power management solution, with the capabilities to sequence, configure, control and monitor power in a compact package. It offers high efficiency and robust protection features while being cost-effective and power efficient. This makes it a great choice for applications requiring reliable and efficient power management.
