Product Summary
The TPS61140DRCR is a dual output boost converter IC. It is intended to be configured as a highly integrated power solution providing regulated voltage and current output with one boost converter. This device is ideal for driving the OLED sub display and WLED backlight for the LCD main display in clam shel phones. The voltage and current can be individually programmed through external resistors. There is a dedicated selection pin for each output, so the two outputs can be turned on separately or simultaneously. The applications of the TPS61140DRCR include Clamshell Phone With OLED/LCD Screen.
