MAX8770GTL+

Overview

The MAX8770GTL+ is a switching controller designed for notebook CPU power supplies, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates in a non-isolated buck topology with a single output capable of adjustable voltage up to 1.5 V. The device supports a maximum duty cycle of 100% and functions at a switching frequency of 600 kHz. It features a shutdown control input and draws a typical operating supply current of 5 mA at a 5 V supply voltage. The component is rated for an extended temperature range from -40°C to +105°C and is housed in a 40-lead TQFN surface-mount package.

Feature Summary

• Designed specifically as a power supply controller for notebook CPUs
• Integrates Intel IMVP6+ multi-phase PWM control capabilities
• Supports high-efficiency buck conversion with 100% maximum duty cycle

Applications

• Notebook CPU core power supplies
• Intel IMVP6+ compatible processor power delivery systems
• Multi-phase DC-to-DC converter designs for mobile computing

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS standards and check for any product discontinuance notifications prior to finalizing procurement plans.

Selection Notes

Select this component when designing power stages for notebooks requiring Intel IMVP6+ compatibility. Consider the 600 kHz switching frequency and 40-lead TQFN package constraints. Evaluate thermal performance within the -40°C to +105°C operating range and ensure the single-output architecture meets the target CPU voltage requirements.

Part Context

The MAX8770GTL+ belongs to the MAX8770 series of specialized power management ICs. It is categorized under PMIC - Power Management ICs and Switching Controllers. This component serves as a dedicated solution for mobile processor power regulation, distinct from general-purpose regulators by its integration of specific interface protocols and phase control logic.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if other members of the MAX8770 series or newer generations from Analog Devices offer pin-compatible alternatives.
