Frequently Asked Questions
How many LED output channels does TPS61151DRCT provide, and how is brightness controlled?
The TPS61151DRCT provides 2 constant-current LED output channels whose drive current is programmed via a serial data interface, eliminating the need for multiple PWM GPIO lines from the host microcontroller. This serial control scheme allows smooth brightness stepping across a wide range, making it suitable for 8-bit or higher dimming resolution in portable display backlight designs operating from a single Li-ion cell.
What package does TPS61151DRCT use, and how does it benefit compact display module layouts?
TPS61151DRCT is housed in a 10-pin WSON (SON) package with a 3×3 mm body, which fits within the tight space constraints typical of thin smartphone or wearable display modules. The small footprint, combined with just 2 control pins required from the host processor, reduces the total board area occupied by the LED driver sub-circuit by up to 40% compared to discrete transistor-based solutions.
For a wearable fitness tracker display, why would a designer choose TPS61151DRCT over a single-channel LED driver?
A wearable fitness tracker often drives 2 separate LED zones—for example, a status indicator and a main LCD backlight—simultaneously at different current levels. The TPS61151DRCT handles both channels from a single IC, saving at least one additional driver IC, 4 to 6 passive components, and 2 PCB mm² compared to using two independent single-channel drivers, while the serial interface keeps GPIO usage at just 2 pins regardless of how many channels are active.
