1. Describe
The TPS92692 and TPS92692QPWPTQ1 feature high precision Peak current mode based controllers designed for Boost/buck LED driver topology is supported. This The device integrates a rail-to-rail current amplifier to Measure LED current and spread spectrum frequency modulation techniques to improve EMI performance. This high- performance LED controller can Use either to independently modulate the LED current Analog or PWM dimming technology. Linear simulation Get Dimming Response Over 15:1 Range By changing the voltage across the high impedance Analog Adjustment (IADJ) input. PWM dimming of LEDs current is achieved by direct modulation DIM/PWM input pin with desired duty cycle or via Enables the internal PWM generator circuit. This The PWM generator converts the DC voltage to DIM / PWM pin through the corresponding duty cycle Compare this to the internal triangle wave generator. An optional PDRV gate driver output can be used for Drives external P-channel series MOSFETs. TPS92692 and TPS92692-Q1 device support Pass current continuous LED status check Monitor (IMON) output. The device also includes a Open-drain fault indicator output to indicate LED Overcurrent, Output Overvoltage and Output undervoltage condition.

5. Application Information
The TPS92692 and TPS92692-Q1 controllers are suitable for implementing step-up or step-down LED driver topologies including boost, buck-boost, SEPIC, and flyback. Use the following design procedure to select component values for the TPS92692-Q1 device. This section presents a simplified discussion of the design process for the boost and buck-boost converter. The expressions derived for the buck-boost topology can be altered to select components for a 1:1 coupled-inductor SEPIC converter. The design procedure can be easily adapted for flyback and similar converter topologies.
