MP8850

MP8850

2.9V to 5.5V, 30A, Stackable, High-Efficiency, Synchronous Buck Converter with I²C Interface

Description

The MP8850 is a fully integrated, stackable, synchronous buck converter with an I²C interface. It provides a complete power solution that integrates the control and power stage, offering excellent efficiency across a wide load range.

By adopting MPS’s proprietary, multi-phase constant-on-time (MCOT) control, it provides ultra-fast transient response and minimizes the required output capacitance (C_OUT). The I²C interface provides digital configurability and key parameter monitoring.

The device features full protection functions, including over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-voltage protection (OTP).

The MP8850 is available in a compact LGA-26 (3mmx4mm) package.
