Frequently Asked Questions
What are the output voltages of the LM3687TL-1815/NOPB?
The LM3687TL-1815/NOPB provides two fixed regulated output voltages: 1.8V and 1.5V. The 1.8V output typically powers RF transceivers, I/O interfaces, and LPDDR memory, while the 1.5V output supplies digital logic cores, baseband processor cores, or low-voltage DDR memory in mobile handset designs. The dual-rail configuration eliminates the need for two separate converter ICs.
What is the input voltage range of the LM3687TL-1815/NOPB?
The LM3687TL-1815/NOPB accepts input voltages from 0.7V minimum to 5.5V maximum, making it compatible with a single-cell Li-ion battery that can discharge from 4.2V fully charged down to below 3V. The very low 0.7V minimum input allows the converter to continue operating even as the battery approaches full discharge, maximizing runtime in mobile devices.
What package is the LM3687TL-1815/NOPB available in?
The LM3687TL-1815/NOPB is housed in a 9-ball micro-SMD (uSMD) BGA package, JESD-30 code R-XBGA-B9, which is an extremely compact package designed specifically for mobile phone PCBs where component density is critical. The uSMD BGA format occupies less than 2 mm² of board area, enabling integration into tight PCB regions around the RF and baseband chipsets.
What control method does the LM3687TL-1815/NOPB use for voltage regulation?
The LM3687TL-1815/NOPB uses PWM (Pulse Width Modulation) voltage-mode control, which provides stable, low-ripple output voltage regulation with predictable loop dynamics. Voltage-mode PWM control is well suited for designs requiring tight load regulation and low output voltage ripple for sensitive RF, analog, and DDR memory power rails in mobile and wireless communication devices.
