Technical content

BM0150HV 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. BM0150HV is available in standard TO-263,TO252 and PSOP-8 with power pad package.

The green additional protect circuit is optional for special application. There is also low dropout circuit available outside of chip, for example, when the input +12V drop to +6V or even +5V, the output 5V can still output 5V.
