MPQ7200GLE Description
The MPQ7200 is a high-frequency, constantcurrent, buck-boost LED driver with integrated power MOSFETs. It offers a very pact solution to achieve up to 1.2A of continuous output current, with excellent load and line regulation across a wide input supply range. The MPQ7200 can also be configured for buck mode to provide up to 3A of constant load current.
