SY7301ADC数据手册Silergy中文资料规格书

描述 Description

SY7301 is step-up DC/DC converters that deliver an accurate constant current for driving LEDs. Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the external resistor. The SY7301 is ideal for driving up to ten white LEDs in series or up to 40V.
