It integrates two outputs capable of delivering 600 mA per channel during flash, controlled via an I²C interface for precise dimming and timing. The 2 MHz switching frequency allows the use of small external inductors and capacitors, saving board space in compact camera modules. ## Supply range and thermal limits The device operates from a 2.5 V to 5.5 V supply, compatible with single-cell Li-ion batteries common in portable cameras. The -30°C to 85°C ambient temperature range covers consumer and industrial handheld devices, though the upper end may be tight for enclosed designs with high ambient heat — watch the thermal derating if the flash fires repeatedly in a warm chassis. ## Package and mounting Housed in a 16-bump DSBGA package, the LM3554TMX/NOPB requires a well-controlled SMT process and X-ray inspection for solder joint verification. ## Sourcing and lifecycle No end-of-life notice or last-time-buy window is currently in effect, making it suitable for both new designs and ongoing production.","metaTitle":"Texas Instruments LM3554TMX/NOPB LED Driver, DC-DC Boost","metaDescription":"Texas Instruments LM3554TMX/NOPB DC-DC boost regulator for camera flash.
