The TPS92692QPWPRQ1 is a high precision peak current mode based controller designed to support buck-boost LED driver topologies. The device integrates a rail-to-rail current amplifier to measure LED current and spread spectrum frequency modulation technique to improve EMI performance.

The TPS92692QPWPRQ1 is a high-performance LED controller that independently modulates LED current using analog or PWM dimming techniques. A linear analog dimming response over a 15:1 range is obtained by varying the voltage at the high impedance analog adjust (IADJ) input. PWM dimming of the LED current is achieved by directly modulating the DIM/PWM input pin with the desired duty cycle or by enabling the internal PWM generator circuit. The PWM generator converts the DC voltage on the DIM/PWM pin to the corresponding duty cycle by comparing it with the internal triangle wave generator. An optional PDRV gate driver output can be used to drive an external P-channel series MOSFET.

The TPS92692QPWPRQ1 device supports continuous LED status checking through the current monitor (IMON) output. The devices also include an open-drain fault indicator output to indicate LED overcurrent, output overvoltage, and output undervoltage conditions.
