The LTC4125IUFD is a specialized power management integrated circuit (PMIC) built by Linear Technology Corporation. It is typically used to provide a regulated voltage supply to multiple processor cores in a single chip processor or to bias a power amplifier. It can also be used to provide single-rail power distribution in small form factor embedded system designs. The LTC4125IUFD features an adjustable Resistor-Settings Digital Voltage Optimizer (DSVO) control circuit, integrated FETs, over-voltage and over-current protection, and integrated inductors. It is designed for use in applications requiring controlled voltage delivery in a small form factor.

The LTC4125IUFD is a synchronous buck regulator tailored for applications that require a high data rate and fast transient response. It features a wide input voltage range of 4.5V to 16V, a 2.5V to 6V adjustable output voltage, and a 10A continuous output current. It supports fast transient times while still maintaining a low output voltage ripple. The integrated switch FETs and inductors reduce component count and simplify circuit design. It includes over-voltage, over-current, over-temperature, and under-voltage protection.

The LTC4125IUFD’s control circuit uses digital control circuitry and voltage feedback to provide fast and accurate load regulation. The voltage feedback is compared to an internal reference voltage and used to adjust the duty cycle of the boost converter. The output voltage can be adjusted using the on-chip resistor network. A soft-start capacitor is included to reduce in-rush current. The LTC4125IUFD draws only 1mV ripple under all load conditions.
