Summary high frequency boost converter, 8-SON, -0.3 V to 7 V, 1 MHz
Description as follow:
The TPS61043DRBR is a high frequency boost converter with constant current output that drives white LEDs or similar. The LED current is set with the external sense resistor (RS) and is directly regulated by the feedback pin (FB) that regulates the voltage across the sense resistor RS to 252 mV (typ). To control LED brightness, the LED current of TPS61043DRBR can be pulsed by apply-ing a PWM (pulse width modulated) signal with a frequency range of 100 Hz to 50 kHz to the control pin (CTRL). The applications of the TPS61043DRBR include White LED Supply for Display Backlight/Sidelight in PDA, Pocket PC, Smart Phones, Handheld Devices, Cellular Phones.
