Frequently Asked Questions
What output voltage does the LM2757TMX/NOPB provide?
The LM2757TMX/NOPB is a regulated voltage doubler that produces approximately 2× the input voltage, up to a maximum of 5.5V output. From a 3.3V input it can deliver a regulated 5V output at up to 200mA for USB or display driver applications.
What is the maximum output current of the LM2757TMX/NOPB?
The device delivers up to 200mA regulated output current, sufficient for driving white LED backlights, small OLED displays, and auxiliary 5V rails in portable electronics. Output current capability decreases at lower input voltages.
Why use a charge pump instead of a buck-boost converter?
The LM2757 charge pump requires no inductor — only small ceramic flying and output capacitors. This eliminates magnetic EMI, reduces total solution height to under 1mm, and simplifies PCB layout. Ideal when board height and area are critical constraints.
What is the package size of the LM2757TMX/NOPB?
The device uses a 6-bump DSBGA (Die-Sized Ball Grid Array) wafer-level package measuring only 1.3mm x 0.9mm x 0.5mm. This is one of the smallest power converter packages available, enabling placement in ultra-compact wearables and earbuds.
What applications use the LM2757TMX/NOPB?
Common applications include white LED backlight drivers for portable displays, OLED panel voltage bias generation, USB 5V rail generation from 3.3V battery, and auxiliary power in space-constrained wearables, hearables, and miniature IoT sensor nodes.
