The Future of Analog IC Technology DESCRIPTION The MP1400 is a monolithic negative DCDC power converter with built-in internal power MOSFET. The DC-DC IC has a tiny surface mount 0.8mm x 1.6mm 8-ball CSP package. It achieves up to 600mA peak output current from a 2.7V to 7V input voltage. The output voltage can be regulated from -0.9V to -6V. The 1500 kHz switching frequency allows for smaller external components producing a compact solution for a wide range of load currents. The internal compensation and soft start minimizes the external component count and limits the inrush current during startup. Fault condition protection includes cycle-bycycle current limiting and thermal shutdown. MP1400 7V Input, 0.6A Peak, 1.
