Product Overview
The LP5523 is a Texas Instruments nine-channel LED driver for systems that need individually controlled LED current source outputs. Outputs D1 to D9 support a 25.5 mA full-scale LED output current, 8-bit programmable LED current setting, and 12-bit PWM brightness control. LED driver operation is specified with a 312 Hz typical switching frequency, 45 mV typical LED output saturation voltage at 17.5 mA, and 1% typical output current matching at 17.5 mA.
Power conversion is handled by an adaptive fractional charge pump with 1x and 1.5x gain modes. Datasheet parameters include up to 94% charge pump efficiency, up to 93% LED drive efficiency, 1.25 MHz typical charge pump switching frequency, and 100 us typical VOUT turn-on time at VDD = 3.6 V and IOUT = 60 mA. Recommended charge pump load current is 0 mA to 100 mA.
The device is supplied in a 25-pin DSBGA/YFQ package with a 2.26 mm x 2.26 mm nominal body and 0.4 mm pitch. It operates from 2.7 V to 5.5 V VDD, supports logic pins from 0 V to VDD, and uses an I2C-compatible two-wire interface with four ASEL0/ASEL1 pin-selectable addresses.

Procurement Notes
When requesting a quote for LP5523, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
