LP5527TL/NOPB-Tiny LED Driver for Camera Flash and 4 LEDs with I2C Programmability, Connectivity Test

The LP5527 is a lighting management unit for handheld devices with I2C compatible control interface. The LP5527 has a step-up DC-DC converter with high current output, and it drives display and keypad backlights and powers the camera flash LED. In addition, the DC-DC converter has the output current to power, for example, an audio amplifier simultaneously. The chip has four 8-bit programmable high-efficiency constant-current LED drivers and a flash LED driver. Built-in audio synchronization feature allows the user to synchronize one of the LEDs to audio input.

The LP5527 has an integrated 400-mA flash driver with a safety stop feature and 50-mA torch mode. An external enable pin is provided for synchronizing the flash with the camera action. An external software-independent test interface provides a fast way to find a broken path or short on LED circuits. Very small DSBGA package together with minimum number of external components is a best fit for handheld devices.
