Frequently Asked Questions
How many LED outputs does the LTC3220IPF#PBF support and what is the maximum total output current?
The LTC3220IPF#PBF provides 18 independent LED output channels with a combined maximum total output current of 360 mA. Each channel can be individually programmed via the serial interface, allowing flexible current distribution across LED strings for backlighting, indicator, or display applications.
How does the serial interface of the LTC3220IPF#PBF simplify control of 18 LED channels?
The LTC3220IPF#PBF uses a 2-wire serial data input mode, enabling a microcontroller or FPGA to update current settings for all 18 channels through a compact bus interface with minimal GPIO usage. This eliminates the need for 18 individual PWM pins and allows dynamic brightness adjustment, on/off sequencing, and fault detection from a single software register map.
What package does the LTC3220IPF#PBF use, and how does it affect thermal performance in portable designs?
The LTC3220IPF#PBF uses a 28-pin QFN (S-XQCC-N28) package, which provides an exposed thermal pad on its underside for direct heat transfer to the PCB copper pour. This allows the driver to dissipate heat efficiently at up to 360 mA total current within the small footprint required by smartphones, tablets, and wearable devices.
For which LED configurations is the LTC3220IPF#PBF a better fit than a single-output LED driver?
The LTC3220IPF#PBF is a better fit than a single-output driver whenever a design requires 2 or more independently controlled LED strings — such as RGB keypad lighting (3 color channels), multi-zone backlight arrays (up to 18 segments), or status indicator panels combining 3 V and 5 V LEDs. Consolidating up to 18 channels into 1 chip reduces both component count and PCB routing complexity compared to using multiple discrete single-output drivers.
