MPQ3414BGJ-5-AEC1-P

MPQ3414B is a high-efficiency, synchronous, current-mode step-up converter with output disconnect. The MPQ3414B can start up from an input voltage (VIN) as low as 1.8V, while also 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. If the MPQ3414B shuts down, then the P channel MOSFET disconnects the output from the input. Output disconnect discharges the output completely, which allows the MPQ3414B to draw a supply current (ISD) below 1μA during shutdown. The 2.2MHz fixed switching frequency (fSW) allows for the use of small external components. Internal compensation and soft start (SS) reduce the number of external components required. These features provide a compact solution for a wide current load range. Applications include single-cell li-ion backup batteries, automotive secondary regulation.
