TPS92692QPWPRQ1 Description

The TPS92692QPWPRQ1 High Accuracy   LED Controller from Texas Instruments is designed to work with step-up/down LED driver topologies. To monitor LED current, each device has a rail-to-rail current amplifier, as well as a spread spectrum frequency modulation approach for better EMI performance. Using analog or PWM  dimming techniques, this LED controller may independently modify the LED current,  Varying the voltage across the high impedance analog adjust (IADJ) input produces a linear analog dimming response with a range of over 15:1. PWM  dimming of LED current can be accomplished by either directly modulating the DIM/PWM input pin with the required duty cycle or by turning on the internal PWM  generator circuit. By comparing the DC voltage at the DIM/PWM pin to the internal triangle wave generator, the PWM  generator converts it to the corresponding duty cycle.
