DESCRIPTION

A7425 is a wide input voltage, high efficiency current mode Synchronous step-down DC/DC converter. A7425 provides up to 2.5A output current at 500kHz switching frequency.

A7425 integrates a 130mΩ high side and an 80mΩ low side MOSFET to achieve high conversion efficiency up to 96. The current mode control architecture supports fast transient response and simple compensation circuit.

Protection features include cycle-by-cycle current limit, thermal shutdown, and short circuit protection.

The A7425 is available in SOP8 package.
