MAX1515ETG+

Special Purpose Regulators Overview

The MAX1515ETG+ is a low-voltage, internal switch, step-down switching regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 1.3 V to 3.6 V and provides a single adjustable output from 500 mV to 2.7 V. The device delivers up to 3 A of output current at a fixed switching frequency of 1 MHz. It features a TQFN-EP-24 package for surface mount installation and supports an operating temperature range from -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Integrates an internal power switch within a compact footprint to minimize external component count.
• Utilizes a fixed 1 MHz switching frequency to allow for the use of small inductors and capacitors.
• Supports low input voltages starting at 1.3 V for efficient operation in battery-powered systems.

Special Purpose Regulators Applications

• Portable electronics requiring efficient voltage conversion from single-cell lithium-ion sources
• Battery-operated devices needing regulated low-voltage rails
• Embedded systems utilizing buck topology for power management

Special Purpose Regulators Procurement Notes

Verify the specific suffix ETG+ against official manufacturer documentation to confirm the TQFN-EP-24 package and lead-free status. Ensure compatibility with your PCB layout requirements for the exposed pad thermal connection. Cross-reference the full part number with authorized distributors to confirm current availability and authenticity before ordering.

Special Purpose Regulators Selection Notes

Select this component when designing circuits that require a 3 A output current from a low input voltage source between 1.3 V and 3.6 V. The fixed 1 MHz frequency is suitable for applications prioritizing small passive component size over ultra-low noise. Verify that the required output voltage falls within the 500 mV to 2.7 V adjustable range and that the thermal performance of the TQFN-EP-24 package meets your system's heat dissipation needs.

Special Purpose Regulators Part Context

This device belongs to the MAX1515 series of low-voltage synchronous step-down regulators. It is designed for applications where space constraints and efficiency are critical. The integration of the switch and control logic simplifies the design process compared to discrete solutions or controllers requiring external MOSFETs.

Special Purpose Regulators Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the Maxim Integrated portfolio. Verify that any replacement maintains the same 1.3 V to 3.6 V input range and 3 A current capability.
