The BD6150MUV-E2 from ROHM Semiconductor is a white LED driver IC designed for medium to large LCD panels. It incorporates a PWM step-up DC/DC converter capable of boosting up to 40V and a current driver that can handle up to 30mA per channel. This device provides wide and precise brightness control through an external PWM pulse.
Key features include high efficiency operation with switching frequencies of 1.25MHz or 0.75MHz, and high accuracy current drivers with good matching between strings, minimizing brightness spots on the LCD. It integrates a 50V power Nch MOSFET and supports driving up to 10 LEDs in series across 6 strings in parallel. The wide input voltage range is from 4.2V to 26V.
Safety functions are integrated, including over-voltage protection, over-current limit, LED terminal open/short protection, external SBD open detect/output short protection, UVLO, and thermal shutdown. The BD6150MUV-E2 is housed in a small and thin VQFN024V4040 package measuring 4.0 x 4.0 x 1.0mm, making it suitable for space-constrained applications.
This LED driver is ideal for backlighting in notebook PCs, portable DVD players, car navigation systems, and other medium-sized LCD equipment. The operating temperature range is -40°C to +85°C.

Estimated market price range - modelled values for guidance only, not live distributor offers.
The input voltage range is from 4.2V minimum to 26V maximum, with a typical value of 12V.
It is available in a VQFN020V4040 package (24-VFQFN exposed pad) for surface mount.
The operating temperature range is -40°C to +85°C.
The typical switching frequency is 1.25MHz.
The maximum output current is 30mA.
The typical quiescent current is 1.6µA when PWMPOW is 0V.
The maximum power dissipation depends on board mounting: 500mW without heat radiation board, 780mW on a 1-layer ROHM standard board, and 1510mW on a 4-layer JEDEC compliant board.
