The EV28160-C-00A is an evaluation board for the MP28160, which 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 light-load conditions, it enters auto-PFM/PWM mode to get high light-load efficiency. Integrated MOSFETs minimize the solution size while maintaining high efficiency.

Fault protections include output hiccup current limiting, OVP, and thermal shutdown.

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