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.

TPS92692/TPS92692-Q1 LED Controllers

Texas Instruments TPS92692/TPS92692-Q1 High Accuracy LED Controllers support step-up/down LED driver topologies. Each device incorporates a rail-to-rail current amplifier to measure LED current and spread spectrum frequency modulation technique for improved EMI performance. These LED controllers can independently modulate LED current using analog or PWM dimming techniques. Linear analog dimming response with an over 15:1 range is obtained by varying the voltage across the high impedance analog adjust (IADJ) input. The PWM dimming of the LED current is achieved by directly modulating the DIM/PWM input pin with the desired duty cycle or enabling the internal PWM generator circuit. The PWM generator translates the DC voltage at the DIM/PWM pin to the corresponding duty cycle by comparing it to the internal triangle wave generator. The optional PDRV gate driver output can be used to drive an external P-Channel series MOSFET. The Texas Instruments TPS92692-Q1 device is AEC-Q100 qualified for automotive applications.
