1.5A POWER LED DRIVER
DESCRIPTION
FEATURES
BM0150 is a PWM power LED driver IC. The
driving current from few milliamps up to 1.5A. It allows
high brightness power LED operating at high efficiency
from 3.6Vdc to 40Vdc. Up to 200KHz external controlled
operation frequency. External resistor controlled the
maximum output current to single LED or a LED string.
„ Only 5 external components required.
„ Output driving current up to 1.5A.
„ 3.6V~40V wide operation voltage range.
„ High efficiency
„ ESD protection HBM 3KV
„ TO-252 5-pin power package.
APPLICATIONS
„ DC/DC LED driver
„ Automotive
„ Lighting

Note :
Junction Temperature Calculation: TJ = TA+ (PD x θJA).
PD: Power Dissipation, TA: Ambient temperature, θJA: Thermal Resistance-Junction to Ambient
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
