Краткое описание:
High Efficiency Charge Pump for 7 WLEDs with I2C Interface
Дополнительная информация
The TPS60250 is a high-efficiency, constant-frequency charge pump DC/DC converter that uses dual-mode 1x and 1.5x conversions to maximize efficiency over the input voltage range. The device can drive up to five white LEDs for a main display and up to two white LEDs for a sub-display with regulated constant current. It features an I2C interface for fully programmable current with 64 dimming steps (25mA max) for display banks and 4 dimming steps (80mA max) for auxiliary applications.
