Product details

Boost regulator for dual-string LED backlights

Switching at 1.2 MHz, the part keeps external inductor and capacitor values small — a 4.7 µH to 10 µH inductor typically fits the bill, and the 10-VSON (3x3) package saves board area in space-constrained display panels.

PWM dimming and dual-channel independence

PWM dimming is supported directly, so the backlight brightness can be controlled from the system processor without an external PWM generator. Each of the two outputs can be dimmed independently — useful for split-screen displays or dual-LCD panels where one string needs a different brightness level.

Frequently asked questions

Does TPS61150DRCRG4 support PWM dimming?

Yes, PWM dimming is listed as a feature of this regulator. The dimming signal can be applied directly to the control pin, allowing the system processor to set the backlight brightness without additional components.

What is the maximum output current of TPS61150DRCRG4?

Each of the two outputs is rated for 35 mA. The total output power is limited by the boost topology and the input supply — at 27 V and 35 mA per channel, the combined output power is about 1.9 W, well within the device's capability with proper thermal management.

How does TPS61150DRCRG4 compare to TPS61150DRCR?

The TPS61150DRCRG4 and TPS61150DRCR share the same base product number (TPS61150) and identical electrical specifications — 27 V output, 2 channels, 35 mA per channel, PWM dimming, 1.2 MHz switching. The suffix difference indicates packaging or tape/reel variant; the RG4 suffix typically denotes a specific reel quantity or lead-free finish. For a BOM line, either variant is functionally interchangeable, but confirm the exact suffix matches the assembly house's preferred reel quantity and MSL level.
