Overview
The MAX8668ETET+T is a switching voltage regulator from the MAX8668 series, manufactured by Analog Devices Inc./Maxim Integrated. It features a Buck topology with a 1.5 MHz switching frequency. The device provides four outputs: two step-down DC-DC converters and two LDOs, each with individual enables. Output voltages range from 600 mV to 3.3 V, supporting up to 1.2 A output current. It operates within an input voltage range of 2.6 V to 5.5 V and functions between -40°C and +85°C. The component is housed in a TQFN-16 package.
Feature Summary
- Integrates dual synchronous step-down DC-DC converters with dual low-dropout regulators for comprehensive power management.
- Features individual enable controls for each output channel to optimize system power efficiency.
Applications
- Portable electronic devices requiring multi-rail power distribution
- Battery-operated systems utilizing single-cell lithium-ion batteries
- Embedded applications needing compact power management solutions
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be restricted. Ensure ordering suffixes match specific packaging requirements such as cut tape or reel formats before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring integrated dual buck and LDO outputs in a small footprint. Verify that the 1.5 MHz switching frequency aligns with EMI constraints and inductor size requirements. Ensure input voltage ranges accommodate the source supply variations expected in the target application environment.
Part Context
This part belongs to the MAX8668 family of power management ICs designed for space-constrained portable electronics. It consolidates multiple regulation stages into a single TQFN-16 package, reducing board area compared to discrete solutions. The series targets applications demanding high efficiency and flexible output configurations.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult official manufacturer resources for potential cross-reference options if this component is discontinued or unavailable.
