Product Overview
The LP5562 is a Texas Instruments four-channel LED driver for R, G, B, and W LED current-sink outputs. Each of the four channels is independently programmable, with a per-output current setting range from 0 to 25.5 mA in 100 uA steps and 8-bit PWM control resolution. Three program execution engines support autonomous lighting sequences using a flexible instruction set.
The device operates from a recommended VDD supply range of 2.7 V to 5.5 V, while EN/VCC supports 1.65 V to VDD logic supply operation. I2C operation supports a 400 kHz clock frequency, and four pin-selectable addresses are available through ADDR_SEL0 and ADDR_SEL1. A 32 kHz external clock input is supported, with timing requirements defined for high time, low time, rise time, and fall time.
LP5562 is supplied in a 12-pin YQE DSBGA package with 0.4-mm pitch and maximum body size of 1.648 mm x 1.248 mm. Recommended operating limits include -40 degC to 125 degC junction temperature and -40 degC to 85 degC ambient temperature. Thermal shutdown engages at 150 degC typical and releases at 130 degC typical.

Procurement Notes
When requesting a quote for LP5562, 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.
