产品详细说明

TPS92692QPWPRQ1 is a 20-pin HTSSOP automotive LED controller from Texas Instruments that regulates an external switching stage and adds spread-spectrum frequency modulation.

The spread-spectrum function distributes switching energy across frequency, helping a vehicle lamp design address conducted and radiated interference without relying only on output filtering.

A rail-to-rail LED-current amplifier and buck, boost or related topology choices let the designer match the power stage to string voltage while maintaining better than four-percent current accuracy under the specified junction-temperature range.

Its internal voltage-to-PWM generator can create dimming from an analog control level, while a direct PWM input and optional external series FET support wider contrast when the host already supplies timing.

Current monitoring and an open-drain fault flag expose abnormal LED or power-stage conditions to the automotive controller.
