FTM / Connectivity / ROHM — BD28C5xH_LFJ-LB Power Controller
ROHM has released a new family of PWM controller ICs for auxiliary dc-dc power supplies in
industrial applications.
The BD28C5xH/LFJ-LB controllers have tight, accurate electrical characteristics which enable power-system designers to reduce component count and bill-of-materials cost while improving system performance.
The variants in the BD28C5xH/LFJ-LB family offer different under-voltage lockout thresholds, making them suitable for different types of power switch and providing valuable design flexibility.
The power controllers are pin-compatible with competing controllers available on the market today. The controllers are supplied in an SOP-J8 package measuring 4.9 mm x 6.0 mm x 1.65 mm.
Part Number | Under-voltage Lockout Threshold | Target Power Device Type |
BD28C55FJ-LB | 8.4 V/7.6 V | Silicon MOSFET |
BD28C54FJ-LB | 14.5 V/9.0 V | Silicon MOSFET or IGBT |
BD28C57LFJ-LB | 18.8 V/14.5 V | Silicon carbide MOSFET |
BD28C57HFJ-LB | 18.8 V/15.5 V | Silicon carbide MOSFET |
