The TPS92638QPWPRQ1 is an eight-channel linear LED driver with PWM dimming control. Its design is ideal for driving multiple LED strings to the mid-range power range.

The TPS92638QPWPRQ1 device can drive up to eight light strings with one to three LEDs on each string, with a total current of up to 70mA per channel. Multiple outputs can be paralleled to provide up to 560mA drive current.

TPS92638QPWPRQ1 In multi-string applications, the advantage of this device is that it supports common-cathode connection of LED strings. Therefore, for systems with low-side current sensing, only one return wire is required instead of one for each LED string.

TPS92638QPWPRQ1 This device has the ability to switch the LED current between high current and low current, suitable for parking light and tail light applications. These two LED current levels can be set for each output through two reference resistors.
