DC/DC converter cuts space in led lighting applications
Diodes' new miniature dc/dc converter supports boost, buck and voltage inverting circuit topologies for led lighting and general purpose power management applications.
The AL8811 is available in a 3.0 x 4.9 x 1.1mm MSOP-8L package and requires minimal external components, enabling reductions in both circuit footprint and bom cost.
With a wide 3 to 20V input voltage operating range and an output voltage up to 36V, the module is suitable for an array of different 12V ac lighting applications. Its shut down current is also low at 0.01µA typical, while its maximum output switch current is rated at 1.6A.
Additional features include an internal temperature compensated reference, a controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch.
