MP4582

MP4582

100V, 2A, 8μA I_Q, Synchronous Step-Down DC/DC Converter

概要

The MP4582 is an 8μA quiescent current (I_Q), synchronous step-down converter with integrated high-side and low-side MOSFETs (HS-FET and LS-FET, respectively). It supports up to 2A of output current (I_OUT) with internal compensation.

High power conversion efficiency across a wide load range is achieved through power-save mode (PSM) and a low I_Q under light-load conditions to reduce the switching and gate driver losses.

To achieve a small output ripple at light loads, pull the MODE/SYNC pin high to set the part to forced continuous conduction mode (FCCM). The switching frequency (f_SW) is always fixed at 400kHz for all load conditions.

Full protection features include over-current protection (OCP), short-circuit protection (SCP) with hiccup mode, input voltage (V_IN) and output voltage (V_OUT) over-voltage protection (OVP), and over-temperature protection (OTP).

The MP4582 is available in a QFN-19 (3mmx5mm) package.

EV4582-QVE-00A 100V, 2A, 8μA I_Q, Synchronous Step-Down DC/DC Converter Evaluation Board

The EV4582-QVE-00A is an evaluation board designed to demonstrate the capabilities of the MP4582, an 8μA quiescent current (I_Q), integrated synchronous step-down converter. It supports up to 2A of output current (I_OUT) with internal compensation.

The MP4582 provides high power conversion efficiency across a wide load range, which is achieved via power-save mode (PSM) and its low I_Q under light-load conditions. This reduces switching and gate driver losses. To achieve low output ripple at light loads, pull the MODE/SYNC pin high to enter forced continuous conduction mode (FCCM). The frequency is always fixed at 400kHz under all load conditions.

The MP4582 is available in a QFN-19 (3mmx5mm) package.

It is recommended to read the MP4582 datasheet prior to making any changes to the EV4582-QVE-00A.
