MPQ4334J-AEC1

MPQ4334J-AEC1

36V, 0.5A to 4A, Low-EMI, Synchronous Step-Down Converter, AEC-Q100 Qualified

Description

The MPQ4334J-AEC1 is a configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). The device provides 0.5A to 4A of highly efficient output current (I_OUT) with peak current mode control.

The wide 3V to 36V input voltage (V_IN) range and 40V load dump tolerance accommodate a variety of step-down applications in automotive input environments. A 0.5μA shutdown current (I_SD) allows the device to be used in battery-powered applications.

High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (f_SW) under light-load conditions to reduce switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output voltage (V_OUT) is within 94.5% to 105.5% of its nominal value.

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

The MPQ4334J-AEC1 is available in a QFN-15 (2.5mmx3.5mm) package, and is available in AEC-Q100 Grade 1.
