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.

MAX16833 High Voltage HB LED Drivers

Analog Devices MAX16833C and MAX16833D high voltage HB LED drivers, with an integrated high-side current sense amplifier, provide extremely fast PWM current switching to the LEDs with no transient overvoltage or undervoltage conditions. These drivers provide analog dimming using a DC input at ICTRL. The ICs sense the LED current at the high side of the LED string. The MAX16833 features a +5V to +65V wide input voltage range with a 65V max boost output. The high-side current sensing combined with a p-channel dimming MOSFET allows the positive terminal of the LED string to be shorted to the positive input terminal or negative input terminal without any damage. This Analog Devices MAX16833 series is ideal for automotive exterior lighting as well as a variety of commercial, industrial, and architectural lighting applications.
