BM0152HV

BM 60V LED DRIVER BM0152HV- buck LED driver with 5000:1 dimming DESCRIPTION The BM0152HV is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. The device operates from an input supply between 7V and 60V and provides an externally adjustable output current of up to 1A. Depending upon the supply voltage and external components, the BM0152HV can provide max. 30 watts of output power. The BM0152HV includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state. The BM0152HV is available in PSOP-8 (ESOP8) with power pad packages.
