MAX1722ELT+T

Voltage Regulators - DC DC Switching Regulators Overview

The MAX1722ELT+T is a synchronous boost DC-DC converter from the nanoPower family, designed for ultra-low quiescent current applications. It operates with an input voltage range of 400 mV to 5.5 V and provides a positive adjustable output up to 2 V. The device features a true shutdown mode that reduces supply current to less than 1 nA. It integrates a 400 mA switch and operates at a fixed 2 MHz switching frequency. Packaged in a compact 6-pin uDFN (2x2 mm) footprint, it supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected package variant matches your PCB footprint requirements precisely.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages are extremely low, starting from 400 mV. It is suitable for designs prioritizing minimal standby power over high output current capabilities. Consider the 2 MHz frequency for size reduction but verify electromagnetic interference compatibility. Compare against non-synchronous alternatives if cost is the primary driver rather than efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Maxim Integrated's nanoPower series, characterized by sub-nanoampere shutdown currents. It complements other regulators in the MAX1722x family, offering specific output voltage and current variations. The uDFN-6 package is standard for space-constrained mobile and wearable applications within the Analog Devices portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible substitutes within the MAX1722x series, such as the MAX17220 or MAX17222, depending on required output voltage and current limits. Verify that any alternative maintains the same 400 mV minimum input requirement and shutdown current specifications.
