MP1400GC-P

MP1400 7V Input, 0.6A Peak, 1.5MHz Negative DCDC Power Converter In 8-ball CSP Package The Future of Analog IC Technology DESCRIPTION FEATURES 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. Wide 2.7V to 7V Operating Input Range Output Adjustable from -0.9V to -6V Up to 600mA Peak Output Current 300mΩ High Side MOSFET On Resistance Default 1.5MHz Switching Frequency Ground Reference Enable Cycle-by-Cycle Over Current Protection Short Circuit Protect with Hiccup Mode Output Voltage Discharge Output Over Voltage Protection Available in a 0.8mm x 1.6mm 8-ball CSP Package APPLICATIONS    General Negative Voltage HDD Small OLED Panel All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
