STMicroelectronics L6712/L6712A Dual-Phase DC/DC Controller Datasheet
The L6712 and L6712A are dual-phase step-down controllers optimized for high current DC/DC applications, featuring a 180-degree phase shift between phases. The devices support output voltage programming from 0.900V to 3.300V via an integrated DAC or an external reference, and include programmable remote sense amplifiers to recover losses along distribution lines.
Key features include integrated high-current gate drivers capable of up to 2A, ultra-fast load transient response, and comprehensive protection mechanisms such as crowbar latched overvoltage protection, non-latched undervoltage protection, and overcurrent protection. The oscillators are adjustable externally or fixed internally at 150kHz, and the devices are available in SO-28 and VFQFPN-36 packages.
