Frequently Asked Questions
What input voltage range does MAX1723EZK+ support and from which battery configurations can it operate?
MAX1723EZK+ accepts an input voltage from 1.2 V to 5.5 V, enabling operation directly from a single alkaline cell at 1.2 V, two alkaline cells in series, or a single Li-ion cell, making it versatile for diverse portable power rail designs.
How does the 5-pin SOT23 package of MAX1723EZK+ benefit space-constrained portable PCB designs?
The 5-pin SOT23 package occupies approximately 3 mm × 1.75 mm of board area, one of the smallest footprints available for a switching regulator, which is critical in handheld medical instruments, wearable electronics, and coin-cell powered sensor nodes where every square millimeter matters.
What control technique does MAX1723EZK+ use and why does it matter for battery-powered designs?
MAX1723EZK+ uses voltage-mode pulse-width modulation (PWM) control, which provides stable regulation under varying load conditions and delivers higher efficiency compared to linear regulators when boosting a 1.2 V to 1.5 V battery input up to a 3.3 V or 5 V system rail.
What is the lifecycle and introduction date for MAX1723EZK+, and should buyers be concerned about long-term supply?
MAX1723EZK+ was introduced in July 2001 and carries a YTEOL of 9 years, indicating continued production availability from Analog Devices; buyers planning multi-year portable product programs should verify current distributor stock and place blanket orders accordingly.
