SL0150HV

产品详情

DESCRIPTION

SL0150HV is the monolithic IC designed for

step-down LED driver capable of driving
1.8A-3.3A load without additional transistor.
The input voltage range is up to 60V. Its
feedback voltage, VFB, is 200mV. The chip
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. SL0150HV is available in standard

TO-263,TO252 and PSOP-8 with power pad package.
