The Texas Instruments TPS61140DRCT is a highly integrated dual output boost converter IC. It is designed to provide regulated voltage and current output using a single boost converter.
This device is ideal for applications such as driving the OLED sub-display and WLED backlight for LCD main displays in clamshell phones. It supports an input voltage range of 2.5 V to 6 V and can provide two outputs, each up to 27 V. The integrated switch handles up to 0.7 A.
The TPS61140DRCT operates at a 1.2 MHz PWM switching frequency for WLED driving and uses PFM for the OLED supply, optimizing efficiency across a wide load range. It features individually programmable outputs, allowing them to be turned on separately or simultaneously. The device also supports up to 30 kHz PWM dimming frequency for WLED dimming.
Packaged in a 10-pin, 3x3 mm QFN (VSON) package with an exposed thermal pad, this component offers a compact solution with built-in power MOSFET and power diode, eliminating the need for external active power components. It includes features like short-circuit protection and overvoltage protection.
