MP3414AGJ-P

MP3414A 3A, 1MHz, 22μA Iq, 5.5V Synchronous Step-Up Converter with Output Disconnect The Future of Analog IC Technology DESCRIPTION FEATURES The MP3414A is a high-efficiency, synchronous current mode, step-up converter with output disconnect.           The MP3414A can start up from an input voltage as low as 1.8V while providing inrush current limiting and output short-circuit protection (SCP). The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The PMOS disconnects the output from the input when the MP3414A shuts down. The output disconnect feature allows the output to be discharged completely, allowing the MP3414A to draw a supply current of under 1μA in shutdown mode. The 1MHz switching frequency allows small external components while the internal compensation and soft start minimize the external component count. These features produce a compact solution for a wide current load range. The MP3414A features an integrated power MOSFET that supports an output of up to 5.5V and a peak switching current above 3A. The MP3414A is available in a small 8-pin TSOT23 package.    Supports 5V/1A Output at 2.8V Input 1.8V to 5.5V Input Voltage Range Up to 5.5V Output Voltage Internal Synchronous Rectifier 1MHz Fixed Switching Frequency 22μA Quiescent Current
