MP7200GLE-Z

MP7200 is a high frequency, constant current, buck-boost LED driver with integrated power MOSFETs. It offers a very compact solution to achieve up to 1.2A of continuous output current, with excellent load and line regulation across a wide input supply range. The MP7200 can also be configured to buck mode to provide up to 3A of constant load current. The switching frequency goes up to a fixed 2.3MHz in buck mode to reduce the current ripple and improve EMI and down to 1.15MHz in buck-boost mode to optimize efficiency and thermal performance. Full protection features include undervoltage (UV), thermal derating (TD) and thermal shutdown (TSD). The fault indicator outputs an active logic low signal if a fault condition occurs. MP7200 requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-19 package. Applications include turn indicator lights, daytime running lights (DRLs), fog lights and rear lights.
