DESCRIPTION
 
The MP3212 is a high efficiency, fixed frequency, current-mode boost converter with input disconnect, inrush current limiting, internal soft-start and compensation. The 1MHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. The input disconnect feature provides complete isolation from output to input when the device is in either shutdown mode or fault condition. The internal compensation minimizes the external component count and soft-start limits the current during startup. The MP3212 automatically transitions into pulse-frequency modulation mode to achieve better efficiency at light load. The input voltage range of 2.3V to 5.5V can generate 28V at up to 100mA. The MP3212 includes under-voltage lockout, current limit, over voltage protection and thermal shutdown. In addition to cycle by cycle current limit at power switch, the average current is also monitored at disconnect switch to prevent damage in the event of output overload. The MP3212 is offered in a compact 10-pin QFN (3mm x 3mm) package.
