LM36274: Looking for a power supply o support LCD bias and WLED backlight

Part Number: LM36274



I’m looking for a DC-DC boost converter for TFT LCD bias and backlight. Input is +12V or +5V, output is +24(5mA), -6V(5mA) for LCD bias and 21V(200mA) for backlight.

I see TI has such part, such as LM36274, but its output is +/-4V ~ +/-6.5V for LCD bias.

Can you please recommend a part for my application?
