The EMP2112 device is a synchronous step-down buck DC-DC converter optimized for high  efficiency and compact solution size. The device integrates switches capable of delivering an  output current up to 1.2A. At medium to heavy loads, the device operates in pulse width modulation (PWM) mode with 1.5- MHz switching frequency. At light load, the device automatically enters PFM mode to maintain  high efficiency over the entire load current range. In shutdown, the current consumption is reduced to less than 2 μA. The EMP2112 provides an adjustable output voltage via an external resistor divider. An internal  soft start circuit limits the inrush current during startup. Other features like over current  protection, thermal shutdown protection and power good are built-in.  The device is available in a SOT23 package.
