STMicroelectronics PMIC - PMIC - Power Supply Controllers, Monitors - L6611D L6611D

The L6611D is a digitally programmable housekeeping controller designed for use in the secondary side of switching power supplies, particularly in desktop PCs and servers. It operates with standard voltage rails of +3.3V, +5V, and ±12V, and includes an auxiliary supply line. The controller features undervoltage (UV) and overvoltage (OV) detection, along with digital trimming capabilities for precise voltage regulation without the need for external components. Key functionalities include monitoring and controlling the output voltages, providing feedback to primary controllers, and implementing fault protection measures. The L6611D supports both latched and bouncing modes for handling UV and overcurrent conditions. It also integrates reference voltages, error amplifiers, and other essential circuitry, contributing to a reduced external component count. The device is packaged in a 20-pin SO configuration, making it suitable for compact designs.
