The 4 MHz switching frequency keeps the inductor small enough for the tight layout of a camera module PCB, and the 9-DSBGA package (1.6×1.6 mm) fits into the corner of a handset board where real estate is measured in square millimeters. ## 1.5 A flash current and thermal envelope The internal switch handles the full 1.5 A peak current, so no external FET is needed — the bill of materials stays to one inductor, two capacitors, and the IC itself. Fully RoHS3 compliant, with no exemptions expiring; the DSBGA package is lead-free and compatible with standard lead-free reflow profiles.","metaTitle":"LM3642TLX/NOPB DC-DC Regulator, 1.5A Flash, I²C, 9-DSBGA","metaDescription":"Texas Instruments LM3642TLX/NOPB boost regulator, 1.5A flash current, I²C dimming, 4MHz, -40°C to 85°C, 9-DSBGA.
