兼容ZXS00的LED恒流升壓IC
The 6303 is a voltage mode boost converter in the SOT23-6 package.Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor giving minimal losses. Its excellent load and line regulation means that for the full supply range from lithium-ion cells, the LED current will tically change by less than1％Using high efficiency switching transistors or the other general switching transistors with ratings of 20V and higher allow many LEDs to be chained in series for the LED current matching possible.
0.9V to 13V supply range, maxim input voltage to 15V
Pin to pin compatible with ZETEX’s ZSX00
Applications: White LED backlighting for colour LCD panels; General LED backlighting; High performance white LED flashlights; General LED driving from batteries
