High-Frequency, Automotive LLC Transformer Driver for Isolated Power Supplies: MPQ18913
A Solution for Primary-Side Switchers
With MPQ18913, MPS presents a high-frequency, half-bridge transformer driver, designed as a solution for primary-side switchers in isolated power supplies. Its two integrated switching FETS allow the device to support up to 300mA of average input current (IIN) across a wide 5V to 30V input voltage (VIN) range.
DOWNLOAD DATAHSEETWide Switching Frequency Range
The device features a wide configurable switching frequency (fSW) range, which is useful for resonant topologies, such as LLC converters. Full protection features include input over-voltage protection (OVP), over-current protection (OCP), and fault indication. The MPQ18913 also features built-in soft start (SS) to control the inrush current during start-up.
The MPQ18913 is available in a QFN-10 (2x2.5mm) package with wettable flanks.
