Unlike other solutions in which the transformer-compatibility circuitry is tightly integrated with the driver circuity, the MA1077 can be used in parallel to your existing LED driver circuitry. So instead of having to re-design your lamp with new transformer-compatible driver circuitry, you can use your existing driver circuitry together with the MA1077 IC.
The MA1077 uses only analogue circuitry, with no digital switching, so the IC has very low electromagnetic interference levels. The IC has very low power consumption, typically less then 0.25 W. It has a wide operation range from 0.2 W to 25 W.
The MA1077 solution is extremely compact, as few additional components need to be used with the IC. This allows for the production of very small form-factor LED lamps that are transformer compatible, such as LED G4 bi-pins that are the same size as the small halogen bi-pin capsules they replace. The low component count also makes for a cost-effective solution.
The MA1077 is available in a 2-pin SOD-123 package.
