Product Overview
LP5036 operates from a 2.7 to 5.5 V VCC supply and supports recommended OUTx voltages from 0 to 5.5 V. Maximum output current is 25.5 mA per channel across the full VCC operating range, or 35 mA per channel when VCC is at least 3.3 V. Constant-current sink precision is specified with ±5% device-to-device and ±5% channel-to-channel current error.
The device uses a Fast-mode I2C interface up to 400 kHz. Two hardware address pins, ADDR0 and ADDR1, allow up to four devices on the address pins, while EN, SDA, and SCL support 1.8 V, 3.3 V, and 5 V power rails. The 46-pin VQFN (RJV) package has a 6.00 mm × 5.00 mm body, and the VCAP internal LDO output pin requires a 1 µF external capacitor to GND.
LP5036 is suited to RGB LED assemblies, multi-channel indicator arrays, and I2C-controlled LED systems that need phase-shifted PWM, low standby current, and software-defined color-bank control.

Procurement Notes
When requesting a quote for LP5036, 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.
