广技师天河学院DESCRIPTION
溶剂热法The MP3423 is a high-efficiency, synchronous, current–mode, step-up converter with output disconnect.
The MP3423 can start up from an input voltage as low as 2.5V while provide inrush current limiting, and output short-circuit protection. 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 part shuts down.
The 600kHz switching frequency allows for small external components, while the internal compensation and the soft-start minimize the external component count. MP3423 provides small size solution for 5V/3.1A load from a supply voltage down to 2.8V.
The MP3423 is available in 14-pin QFN FEATURES
• 2.5V to 5.5V Input Work Range
