BM0150HV
60V Buck Converter
DESCRIPTION
APPLICATIONS
BM0150HV is the monolithic IC designed for
DC/DC LED driver applications
step-down LED driver capable of driving
Backlighting for flat panel displays
1.8A-3.3A load without additional transistor.
General purpose constant current source
The input voltage range is up to 60V. Its
52KHZ,no noise to Automotive-CAR audio
feedback voltage, VFB, is 200mV. The chip
Chargers
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. BM0150HV is available in standard
TO-263,TO252 and PSOP-8 with power pad package.

Thermal protection
Cycle-by-cycle current limit
BM0150HV can replace AP1509,AP1507,XL7005 without change PCB, the Vfb =0.2V, so need
to modify one of the feedback resistor value.
BM0150HV can output CC-constant current, and can output CVPA-cRoTnsMtaAnRt KvoINltGage.
