Monolithic Power Systems (MPS) MP2384 Synchronous Buck Converters

Monolithic Power Systems (MPS) MP2384 Synchronous Buck Converters are fully integrated high-frequency step-down switch-mode converters. The MP2384 converters operate efficiently over a wide output current load range. These buck converters offer a super-compact solution that achieves 4A of continuous output current over a wide input supply range. The MP2384 synchronous buck converters also offer an adaptive Constant-on-Time (COT) control mode that provides a fast transient response and eases loop stabilization. These converters operate at a 4.5V to 24V wide input voltage range.

The MP2384 converters offer various protection features, including Over-Current Protection (OCP), Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), and thermal shutdown. Applications include flat-panel televisions and monitors, security cameras, portable devices, XDSL devices, digital set-top boxes, monitors, and general purposes.
