MSP430F1101AIPWR 描述
† The D package is available taped and reeled. Add the suffix R to the device type when ordering (e.g., TLC7705QDR). ‡ The PW package is only available left-end taped and reeled (indicated by the LE suffix on the device type; e.g., TLC7705QPWLE).
MSP430F1101AIPWR 特点
The MSP430F1101AIPWR/MSP430F1101AIPWR drive up to nine white LEDs with constant current and high efficiency to provide LCD backlighting in cell phones, PDAs, and other handheld devices. The series connection allows the LED currents to be identical for uniform brightness and minimizes the number of traces to the LEDs. The MSP430F1101AIPWR regulates constant LED current over the entire temperature range. The MSP430F1101AIPWR features an ambient-temperature derating function to avoid over- driving the white LEDs during high ambient tempera- tures, enabling higher drive current below +42C. A single Dual Mode™ input provides a simple means of brightness adjustment and on/off control. Fast 1MHz current-mode PWM operation allows for small input and output capacitors and a small inductor while minimizing ripple on the input supply/battery. Soft-start eliminates inrush current during startup. The MSP430F1101AIPWR/MSP430F1101AIPWR are available in a space- saving, 8-pin, 3mm x 3mm TDFN package.
