The ZXSC310 is a single or multi cell LED driver designed for LCD backlighting applications. The input voltage range of the device is between 0.8 V and 8 V. This means the ZXSC310 is compatible with single NiMH, NiCd or Alkaline cells, as well as multi-cell or LiIon batteries. The device features a shutdown control, resulting in a standby current less than 5µA, and an output capable of driving serial or parallel LED’s. The circuit generates constant power output, which are ideal for driving single or multiple LED’s over a wide range of operating voltages. These features make the device ideal for driving LED’s particularly in LCD backlight applications for Digital Still cameras and PDA’s.
The ZXSC310 is a PFM DC‑DC controller IC designed for LCD backlighting applications. It operates from a single or multiple cells with an input voltage range of 0.8 V to 8 V and provides programmable output current for series or parallel LED configurations. The device features a shutdown control, standby current below 5 yA, and 94 % efficiency.
