Monolithic Power Systems (MPS) MP2460 Synchronous Step-Down Converter

Monolithic Power Systems (MPS) MP2460 Synchronous Step-Down Converter is a high-frequency, step-down switching converter with integrated high-side and low-side power MOSFETs. The device can provide up to 0.6A of output current with current mode control for fast loop response. The device’s wide 4.5V to 45V input voltage range accommodates a variety of step-down applications, and the 1μA shutdown mode quiescent current allows the device to be used in battery-powered applications. The MP2460 uses a high-duty cycle and low-dropout mode when the input voltage is low.

The Monolithic Power Systems (MPS) MP2460 achieves high power conversion efficiency across a wide load range by scaling down the switching frequency under light-load conditions. This feature reduces switching and gate-driving losses. The MP2460 has built-in protection features, such as cycle-by-cycle current limiting, short circuit protection (SCP) with hiccup mode, and thermal shutdown during excessive power dissipation. The MP2460 is available in a TSOT23-6 package.
