CP2136QN-A3 Description

Short technical summary and product information.

The CP2136QN-A3 from Chiphomer Technology is a specialized power management IC designed as a 6-channel LED driver. It operates with a wide voltage range from 2.7V to 5.5V, making it suitable for battery-powered devices. Each channel can deliver up to 20mA with a typical current accuracy of 2%. The device utilizes Auto-Mirror technology to ensure good current matching across parallel LEDs, even with variations in forward voltage.

This LED driver features adaptive switching between 1x and 2x charge pump modes, achieving up to 95% efficiency. It supports 1-wire pulse count dimming with 16 logarithmic steps for precise brightness control. The CP2136QN-A3 is designed for low EMI and low input current fluctuations, requiring minimal external components, including no external inductor. It also includes overcurrent, over-temperature, and overvoltage protection features.

The device is housed in a compact 3mm x 3mm QFN-16L package, suitable for surface mount applications. With a shutdown current of less than 1μA, it is ideal for power-conscious designs. The CP2136QN-A3 is RoHS3 compliant and 100% lead-free.

Applications include mobile phones, digital cameras, MP3 players, PMPs, PNDs, PDAs, and digital photo frames where efficient and controllable LED illumination is required.
