Key Features
- Ultra-wide 0.4 V to 5.5 V input range enables boost conversion from a single alkaline or Li-coin cell down to near-depleted battery voltages
- True shutdown mode cuts output leakage to near zero, extending battery life in always-on IoT sensor nodes with infrequent wake cycles
- Pulse-frequency modulation (PFM) current-mode control maintains high efficiency at light loads below 1 mA, ideal for energy-harvesting and wearable designs
Applications
The MAX17220ENT+ is designed for ultra-low-power IoT devices, wearables, and wireless sensor nodes that operate from a single coin cell or small Li-primary battery with discharge voltage as low as 0.4 V. Its 1.8 V to 5 V programmable output range powers microcontrollers, BLE SoCs, and sensor front-ends from a depleting battery while the true shutdown feature prevents drain when the system is fully off. The tiny 6-bump WLCSP package occupies minimal board area in compact PCB designs for medical patches and industrial asset tags.

Frequently Asked Questions
What input voltage range does MAX17220ENT+ support, and can it start from a nearly dead battery?
MAX17220ENT+ accepts input voltages from 0.4 V to 5.5 V, which means it can start up from a battery discharged to just 400 mV, making it suitable for extending the useful life of CR2032 coin cells and single-cell alkaline AA batteries in IoT sensor designs.
How does the true shutdown feature of MAX17220ENT+ benefit battery-operated devices?
In true shutdown mode, the MAX17220ENT+ disconnects its output from the input completely, reducing leakage current to sub-microamp levels. For a device with a 220 mAh coin cell, this can extend shelf life by months compared to converters that maintain a bias path of 5 µA or more during off-state.
What output voltage range and package size does MAX17220ENT+ offer for space-constrained wearable designs?
The MAX17220ENT+ provides an adjustable output from 1.8 V to 5 V and comes in a 6-bump WLCSP package measuring approximately 0.87 mm × 0.87 mm, which is among the smallest boost converter footprints available and is well suited to wearable patches, hearing aids, and miniature sensor modules.
