Product details

The TI LM36923HYFFR is a DC DC boost regulator for LED backlight applications. It integrates three constant-current outputs each rated for 25 mA, with a maximum output voltage of 38 V. Dimming is handled through I²C or PWM input. The part switches at 500 kHz or 1 MHz. Supply range runs from 2.5 V to 5.5 V.

Lifecycle and ordering

The LM36923HYFFR carries an Active lifecycle status and is ROHS3 compliant. Pricing and stock levels fluctuate; confirm current availability and a firm quote by submitting an RFQ.

Frequently asked questions

What is the closest functional second-source for LM36923HYFFR?

The LM2703MF-ADJ/NOPB is a DC DC boost regulator from TI, but it is a single-output part rated for 0.35 A with an adjustable output voltage, not a fixed 25 mA per channel LED driver. It is not a pin-compatible or direct functional replacement for the LM36923HYFFR's three-channel backlight application.

Does LM36923HYFFR work with 3.3V logic for I²C?

Yes. The supply voltage range is 2.5 V to 5.5 V, so a 3.3 V logic rail is within spec. The I²C interface is designed to operate at those levels.
