DC-DC products are DC input, constant current output LED drives, which are mainly used in the
DC voltage source environment. All 12V/24V/48V/380V DC bus voltage can directly be used with
this series to drive the LED engine(chip). LDD series is Step-Down design. LDB series is Buck-Boost
and LDH is Step-up design. Users can choose a suitable product according to their own DC source
environment. DC Bus design can reduce the risk of electric shock and total cost of system. The
PWM dimming and DALI dimming are also available. Besides, DC-DC driver can be applied to solar
lighting solution with a controller, reducing design issue and optimizing the reliability.
