恒压IC、恒压方案、恒压恒流方案 SL3016

DEscriptION
SL3016 is th e monolithic IC designed for
step-down LED driver capable of driving
1.6A-3.5A load without additional transistor.
The input voltage range is up to 60V. Its
feedback voltage,VFB,is 200mV. Thechip
operates at a switching frequency of 52kHz. The
external shutdown function is controlled by a
logic level on the ON/OFF pin and then the
circuit comes into the standby mode with
ISTBY~50μA (typ.). The ON/OFF pin may be
used for the analog dimming. As the voltage on
the ON/OFF pin is increased from 0.07V to
0.67V, the voltage on the FB pin falls from
200mV to 0. The self-protection features include
a cycle-by-cycle current limit and a thermal
protection.SL3016is available in standard
TO-263,TO252and SOP-8 with power pad package.
