STMicroelectronics, Inc. PMIC - Voltage Regulators - DC DC Switching Controllers L6919ETR

The L6919ETR is a dual-phase DC-DC controller designed for high-performance applications, particularly suitable for powering high current microprocessors and servers. It features a 5-bit programmable output voltage range from 0.800V to 1.550V in 25mV steps, allowing for dynamic voltage adjustment. The controller provides a high output voltage accuracy of ±0.6% and includes integrated high current gate drivers capable of delivering up to 2A gate current, ensuring fast switching and low losses. Protection features include overvoltage and overcurrent protection, with the latter implemented through the lower MOSFET's RdsON or an external sense resistor. The device supports ultra-fast load transient response and offers a digital soft-start function with 2048 steps. The oscillator is adjustable externally and is internally fixed at 200kHz, providing flexibility in design. The L6919ETR is housed in a compact SO-28 package, making it suitable for space-constrained applications.
