Frequently Asked Questions

What is the quiescent current of the MAX77503AEWC+ and why does it matter for battery life?

The MAX77503AEWC+ has a quiescent current of only 9 µA, which is critical for extending battery runtime in IoT sensors, wearables, and other battery-powered devices that spend most of their time in a low-power standby state. A lower IQ means less energy wasted when the load is light or off.

What input and output voltage ranges does the MAX77503AEWC+ support?

The MAX77503AEWC+ accepts an input voltage from 3 V to 14 V and provides an adjustable output voltage ranging from 1.55 V to 13.86 V, making it compatible with single-cell Li-Ion batteries as well as multi-cell packs up to 14 V in battery-powered and industrial applications.

Which package does the MAX77503AEWC+ use and how does it affect PCB design?

The MAX77503AEWC+ is housed in a 12-ball WLCSP package, which enables a very small PCB footprint ideal for space-constrained designs such as wearable devices and compact IoT modules. The BGA layout supports a 1.5A output current with minimal external components at up to 14 V input.

What control technique does the MAX77503AEWC+ use and what are its benefits?

The MAX77503AEWC+ uses current-mode pulse-width modulation (PWM) control, which provides fast transient response and inherent cycle-by-cycle current limiting. This technique supports stable regulation across output loads from light to 1.5A and input voltages from 3 V to 14 V.
