Краткое описание:
White LED Charge Pump Current Source with PWM Brightness Control
Дополнительная информация
The TPS60230 is a fractional charge pump (1x/1.5x) optimized for driving up to 5 white LEDs at 25 mA each for backlight applications. It operates from an input voltage range of 2.7 V to 6.5 V, making it suitable for single-cell Li-Ion battery applications. The device achieves high efficiency through its fractional conversion technique and low-dropout current sources. It features a 1 MHz switching frequency, PWM brightness control, and internal soft-start to limit inrush current.
