HT3420 - 2A 28V Synchronous Buck Converter

General Description

The HT3420 is a monolithic synchronous buck regulator.

The device integrates 95 mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5V to 28V.

Current mode control provides fast transient response and cycleby-cycle current limit.
