AKM2800AB

6A Buck Regulator with Integrated Inductor and Digital Power System Management

The AKM2800 is an easy-to-use, fully integrated, and highly efficient voltage regulator with voltage and temperature reporting. The on-chip pulse-width modulation (PWM) controller and integrated MOSFETs, plus incorporated inductor and capacitors, result in an extremely compact and accurate regulator.

The low-profile package is suitable for automated assembly using standard surface-mount equipment. The ability to program aspects of the operation using the Inter-Integrated circuit (I2C) protocol is unique in this class of product. Developing and optimizing all these elements together has yielded the smallest, most efficient, and fully featured 6A currently available. The built-in protection features include pre-biased start-up, soft-start function, over-voltage protection, over-current protection with current clamp mode, thermal shut-down with auto-recovery.

Furthermore, the AKM2800 provides accurate analog-to-digital converter for output voltage and junction temperature measurement to report the regulator parameters. The host can monitor the information by I2C serial interface.
