A8434EESTR-T Description

Short technical summary and product information.

The A8434EESTR-T from Allegro MicroSystems is a high-efficiency charge pump IC designed for driving white LEDs (WLEDs). It can drive up to six WLEDs, suitable for single or multiple display backlighting, or for main display backlighting combined with a low-current flash/torch.

 

This LED driver IC features a proprietary adaptive control scheme for well-matched WLED current, maintaining high efficiency and low EMI. It offers multi-step dimming control for brightness adjustment. The device operates over a supply voltage range of 2.7V to 5.5V and provides up to 30mA per WLED output.

 

Designed for space-constrained applications, the A8434EESTR-T is available in a 16-QFN/MLP (3x3 mm) package. It supports surface mount installation and is suitable for applications such as backlighting for cellular phones, digital cameras, and portable audio devices.
