It drives up to 13 outputs, making it a fit for backlight or camera flash arrays in handheld devices. Switching at 2 MHz, the part keeps external inductor and capacitor values small — useful when board space in a phone or module is tight. The output voltage range spans 4 V to 5.3 V, which covers the forward voltage of most white LED strings in series. ## PWM dimming and temperature grade Dimming is handled via PWM, which avoids colour shift at low brightness compared to analog current reduction — a detail that matters when the driver is used in camera flash or display backlight. The operating temperature range of -30°C to 85°C covers consumer and some industrial ambient conditions, though not extended automotive. The 36-WFBGA package (supplier device package 36-uSMD) is a fine-pitch BGA; rework requires a hot-air profile suited to the 0.5 mm ball pitch. The part is surface-mount only and ROHS3 compliant. ROHS3 compliance is confirmed. No additional compliance documentation (REACH, UL, IEC) is listed in the record.","metaTitle":"LP39542TLX/NOPB Boost LED Driver, 900mA Switch, 13 Outputs","metaDescription":"Texas Instruments LP39542TLX/NOPB DC-DC regulator LED driver, 13 outputs, 900mA switch, PWM dimming, 2MHz, -30 to 85°C.

The LP39542TLX/NOPB integrates the boost switch and targets higher per-channel current (900 mA switch) for flash or backlight — the two parts are not pin-compatible and serve different drive architectures.
