MAX17511GTL+T

The MAX17511GTL+T from Analog Devices (formerly Maxim Integrated) is a versatile dual-output, step-down, constant on-time Quick-PWM controller. It is specifically designed for VR12/IMVP-7 CPU core power supplies, catering to applications in notebooks, desktops, and servers.

This controller integrates two high-current switching power supplies. Regulator A functions as a three-phase constant on-time architecture for the CPU core, while Regulator B utilizes a constant on-time architecture for the GFX core. The device supports programmable switching frequencies from 200kHz to 600kHz per phase. Key features include output overvoltage protection (OVP), undervoltage protection (UVP), and thermal protection, ensuring reliable operation. When a fault is detected, both outputs shut down.

The MAX17511GTL+T boasts ±0.5% output voltage accuracy over line, load, and temperature variations. It incorporates features like transient-phase overlap and active overshoot suppression to enhance response time and reduce output capacitance. The CPU and GFX outputs are independently controlled, and VID code transitions are managed with precision slew-rate control. The controller is available in a 40-pin TQFN (5x5mm) package, suitable for surface mounting.

This device is compliant with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 1. Its operating temperature range is -40°C to 105°C, making it suitable for demanding environments.
