The PWM signal modulates the LED current on/off at a duty cycle that sets the perceived brightness, while the boost converter stays running. This avoids the colour shift that analog current reduction can cause in white LEDs. The datasheet details the PWM frequency range and the minimum pulse width that guarantees accurate dimming. ## Package and rework — QFN with exposed pad The part comes in a 24-VFQFN with an exposed pad (24-VQFN 4x4 mm). ## Supply voltage and input range Input supply range is 4.2 V minimum to 24 V maximum. We source it against an RFQ — confirm the quantity and target lead time when you request a quote.","metaTitle":"TPS61185RGER 8-channel boost LED driver, 38V output","metaDescription":"TI TPS61185RGER DC-DC boost regulator, 8 outputs at 25mA each, 38V max, PWM dimming, 600kHz-2MHz, QFN-24.
