Monolithic Power Systems (MPS) MP7200 Synchronous Buck-Boost LED Drivers

Monolithic Power Systems (MPS) MP7200 Synchronous Buck-Boost LED Drivers are high-frequency and constant-current drivers with integrated power MOSFETs. These drivers offer a compact solution of 1.2A of continuous output current (I_OUT) across a wide input voltage (V_IN) range, with excellent load and line regulation. The MP7200 drivers feature constant-frequency hysteretic control that provides a fast transient response without loop compensation. In addition, these drivers feature Over-Current Protection (OCP), output Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), thermal derating, and thermal shutdown. The MP7200 drivers require a minimal number of readily available, standard external components and are available in a space-saving QFN-19 (3mm x 4mm) package.
