Frequently Asked Questions
How many regulated output rails does the MAX782CBX+ support simultaneously?
The MAX782CBX+ is a triple-output power-supply controller, meaning it can simultaneously regulate 3 independent DC output rails. This makes it ideal for notebook computers that need separate supply voltages for the CPU core, I/O logic, and memory subsystems, all derived from a single Li-Ion battery input around 7.2V to 21V.
What switching frequency does the MAX782CBX+ operate at, and how does it affect inductor selection?
The MAX782CBX+ operates at a programmable switching frequency up to approximately 300 kHz. Higher switching frequencies allow the use of smaller inductors and capacitors, reducing overall PCB footprint. Designers targeting compact notebook designs typically choose inductors in the 4.7 µH to 22 µH range, balancing efficiency against component size at these frequencies.
Is the MAX782CBX+ a suitable replacement for dual-output controllers in portable computing designs?
Yes, the MAX782CBX+ is a strong upgrade over dual-output controllers because it integrates 3 independent regulated outputs in a single SSOP package, reducing BOM complexity and PCB area. Competing dual-output designs require a second IC for the third rail, adding roughly 50 mA of additional quiescent current and extra routing. The MAX782CBX+ consolidates this into one chip.
What package does the MAX782CBX+ use and how does it simplify PCB layout for a notebook motherboard?
The MAX782CBX+ is offered in a 28-pin SSOP (Shrink Small Outline Package) with a 5.3 mm body width and 0.65 mm pin pitch. This compact 28-pin footprint, combined with integrated gate drivers, reduces the need for external driver ICs, simplifying routing on dense notebook motherboard layouts and enabling a power-management module smaller than 10 cm².
