What are the key features of MAX1722EZK+?

PFM step-up switching regulation from 0.8 V to 5.5 V input enables operation from single alkaline or lithium cells
Ultra-compact 5-pin SOT-23 package minimizes PCB footprint in space-constrained portable device designs
Pulse frequency modulation (PFM) control maintains high efficiency at light loads, extending battery life in standby modes
Fixed-output configuration with minimal external components simplifies design and reduces BOM complexity

What is MAX1722EZK+ used for?

MAX1722EZK+ is designed for battery-powered portable applications such as digital cameras, handheld medical devices, and IoT nodes operating from a single alkaline or lithium cell. Its 0.8 V to 5.5 V input range allows the regulator to continue operating as the cell voltage decays, maximizing usable battery runtime. The PFM control scheme maintains high efficiency at light loads, making it ideal for duty-cycled devices with frequent sleep periods.

Frequently Asked Questions

For a single AAA alkaline cell power supply, how does MAX1722EZK+ sustain boost output as the battery discharges?

MAX1722EZK+ accepts input as low as 0.8 V, continuing to boost output as the alkaline cell voltage decays from 1.5 V down to near end-of-life. This wide 0.8 V to 5.5 V input range maximizes usable energy from each cell, extending runtime in portable devices such as remote sensors and handheld instruments.

How does PFM control in MAX1722EZK+ improve efficiency for IoT devices with intermittent light loads?

Pulse frequency modulation in MAX1722EZK+ reduces switching losses at light loads by modulating switching frequency rather than duty cycle, maintaining high conversion efficiency even when the load draws only microamps. This is critical for duty-cycled IoT nodes that spend most of their time asleep, where the 5-pin SOT-23 regulator must deliver clean output with minimal quiescent draw.

When should a designer choose MAX1722EZK+ over a linear LDO in a battery-powered wearable?

A step-up converter like MAX1722EZK+ is required when the battery voltage falls below the desired output voltage, which a linear LDO cannot achieve. For example, boosting a 1.2 V NiMH cell to a 3.3 V rail demands a boost regulator; MAX1722EZK+'s 0.8 V minimum input covers the full discharge range of the cell, something no LDO can do.
