  • TPS61150 Dual Output Boost Converter Drive Up to 14 WLED Keypad LCD Backlight
    PDF, 70 Kb, Datei veröffentlicht: Jul 5, 2006
    The TPS61150/1 is a high-frequency boost converter with two regulated current outputs for driving white light-emitting diodes (WLED). The reference design and applications examples in this document show the TPS61150 driving up to 14 WLEDs, a keypad, and a LCD backlight application. The two current outputs are ideal for driving WLED backlight for the sub and main displays in clamshell phones.
  • Analog PWM Dimming in White-LED Drivers
    PDF, 539 Kb, Datei veröffentlicht: Dec 21, 2016
    Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LEDdriver devices. PWM dimming takes a rectangle waveform with variable positive duty cycle (D) and adjuststhe LED current proportionally. For many smaller format white LED drivers (7-inch screen size or smaller),the PWM signal is converted to a DC control voltage and made to drive the LED current in
