Product details

Five-channel boost regulator for LED backlight panels

Housed in a 20-DSBGA package measuring 2.04 mm x 1.78 mm. Surface-mount part. Lead-free and ROHS3 compliant.

Switching frequency selection — inductor vs efficiency trade-off

Three switching frequencies: 312 kHz, 625 kHz, and 1250 kHz. Lower frequency reduces switching losses; higher frequency shrinks inductor footprint.

Sourcing and lifecycle

Active lifecycle status from Texas Instruments. No last-time-buy or end-of-life notice in effect. ROHS3 compliant.

Frequently asked questions

Does LP8556TME-E03/NOPB support PWM dimming for automotive backlight?

Yes, the LP8556TME-E03/NOPB supports PWM dimming. However, its operating temperature range of -30°C to 85°C limits it to consumer and indoor industrial use, not automotive under-hood or extended-temperature environments.

Is LP8556TME-E03/NOPB obsolete?

No, the LP8556TME-E03/NOPB has an Active lifecycle status. No end-of-life or last-time-buy notice is in effect.
