Product Description

The MP28160 is an integrated buck-boost converter in a small CSP package. The buck-boost converter can operate from an input voltage above, equal to, or below the output voltage. It uses current mode control with a 1.8MHz fixed PWM frequency to optimize stability and transient response. In a light load condition, it enters auto PFM/PWM mode to get high light load efficiency. Integrated MOSFETs minimize the solution size while maintaining high efficiency.

Fault protection includes output hiccup current limiting, OVP, and thermal shutdown.

The MP28160 is available in a tiny CSP-12 (1.4mmx1.8mm) package.
