TPS92682-Q1 Peak Current-Mode Controller Texas Instruments TPS92682-Q1 Dual-Channel Peak Current-Mode Controller is programmable to operate in constant-voltage (CV) or constant-current (CC) modes. In CV mode, the TPS92682-Q1 can be programmed to operate as two independent or dual-phase boost voltage regulators. The output voltage can be programmed using an external resistor voltage divider and a SPI-programmable 8-bit DAC. In CC mode, the device is designed to support dual-channel step-up or step-down LED driver topologies. LED current can be independently modulated using analog or PWM dimming techniques. Analog dimming with over 28:1 range is obtained using a programmable 8-bit DAC. PWM dimming of LED current is achieved either by directly modulating the PWM input pins with the desired duty cycle or using an SPI-programmable 10-bit PWM counter. The optional PDRV gate driver output can drive an external P-Channel series MOSFET.
