IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.

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.
