MPQ18913

30V, High-Frequency Transformer Driver for Automotive Applications, AEC-Q100

データシート

概要

The MPQ18913 is a high-frequency half-bridge transformer driver. It is ideal for use as the primary-side MOSFET in isolated power supplies for biasing silicon carbide (SiC) field-effect transistors (FETs), silicon FETs, and insulated gate bipolar transistors (IGBTs). The MPQ18913 simplifies an isolated biased supply’s design by integrating the control, switching power stage, and protection circuitry in one device. This typology supports designs with a high isolation voltage and small interwinding capacitance.

The MPQ18913 features soft switching to optimize EMI performance. It supports a wide 5V to 30V input voltage (V_IN) range, and can survive surges of up to 50V.

The device has a wide 400kHz to 5MHz configurable switching frequency (f_SW) range, which reduces the solution size and optimizes efficiency in resonant topologies (e.g. LLC converters).

Full safety and protection features include input over-voltage protection (OVP), over-current protection (OCP), and fault indication. The device’s built-in soft start (SS) controls the inrush current during start-up.

The MPQ18913 is available in QFN-10 (2mmx2.5mm) package with wettable flanks.
