Description

General part information

TPS92638 Series

The TPS92638-Q1 is an eight-channel linear LED driver with PWM dimming control. Its design is ideal for driving multiple strings of LEDs up to a medium power range.

This device can drive up to eight strings with one to three LEDs in each string, at a total current up to 70 mA per channel. Outputs can be in parallel to provide higher-current drive up to 560 mA.

In multiple-string applications, the device offers the advantage of having common-cathode connection of the LED stings. So, there is only a single return wire needed instead of one per LED string that a system with low-side current sense would need.
