MP2462

MP2462

34V, 2A, 800kHz, Synchronous Step-Down Converter

Description

The MP2462 is a synchronous, step-down switching regulator with integrated, internal, high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively). The MP2462 provides 2A of highly efficient output current (I_OUT) with current-mode control for fast loop response. The wide 4.2V to 34V input voltage (V_IN) range accommodates a variety of step-down applications. The low shutdown mode quiescent current (I_Q) allows the MP2462 to be used in battery-powered applications.

High power conversion efficiency across the wide load range is achieved by scaling down the switching frequency (f_SW) at light loads to reduce switching and gate driving losses.

Frequency foldback helps prevent inductor current (I_L) runaway during start-up. Thermal shutdown provides reliable and fault-tolerant operation. A high duty cycle and low-dropout (LDO) mode are provided for battery-powered systems.

The MP2462 is requires a minimal number of readily available, standard external components, and is available in a space-saving TSOT23-6 package.
