Description

General part information

TPS92682 Series

The TPS92682-Q1 is a dual-channel, peak current-mode controller with SPI communication interface. The device is programmable to operate in constant-voltage (CV) or constant-current (CC) modes.

In CV mode, 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 a SPI-programmable 10-bit PWM counter. The optional PDRV gate driver output can be used to drive an external P-Channel series MOSFET.
