Product Summary
The TPS61150DRCR is a high frequency boost converter with two regulated current outputs for driving WLEDs. Each current output can be individuallyprogrammed through external resistors. There is dedicated selection pin for each output, so the two outputs can be turned on separately or simultaneously. The output current can be reducedby a pulse width modulation (PWM) signal on theselect pins or an analog voltage on the ISET pin, resulting in PWM dimming of the WLEDs. The applications of the TPS61150DRCR include Sub and Main Display Backlight in Clam ShellPhones, Display and Keypad Backlight, Up to 14 WLED Driver.
