Description

The HX1344D is a synchronous buck controller with a fast charge protocol controller, and follows Quick Charge 3.0 specification.

HX1344D can operating with a wide input voltage range, the HX1344D achieves 2.4A continuous output current with excellent load and line regulation. The switching frequency is fixed 130kHz.

HX1344D can support the full output voltage range of Class A for Quick Charge 3.0, include 200mV each voltage levels from 2.5V to 12V. It also can support USB type-C device, and automatically detects whether a connected powered device is Quick Charge 3.0 capable before enabling output voltage adjustment.

The HX1344D requires a minimum number of readily available standard external components. Other features include cable compensation, UVLO, OVLO, over current protect and thermal shutdown.

The HX1344D converters are available in the industry standard SOP-8L packages.
