MP3415 Datasheet | Monolithic Power Systems

DESCRIPTION The MP3415 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect. The MP3415 can start up with 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 Pchannel MOSFET disconnects the output from the input when the MP3415 shuts down. Output disconnect discharges the output pletely, allowing the MP3415 to draw a supply current below 1μA in shutdown mode. The 1MHz switching frequency allows small external ponents while internal pensation and soft start minimize the external ponent count, making the MP3415 a pact solution for a wide current load range. The MP3415 features an integrated power MOSFET that supports an output up to 5.5V and a peak switching current above 3.6A. The MP3415 is available in a small QFN-12 (2mmx2mm) package. 3.6A, 1MHz, Synchronous, Step-Up Converter with Output Disconnect FEATURES - 1.8V to 5.5V Input Voltage Range - Output Voltage up to 5.5V - Supports 5V/1.5A at 2.8V Input - Internal Synchronous Rectifier - 1MHz Fixed Switching Frequency - 22μA Quiescent Current - <1μA Shutdown Current - True Output Disconnect from the Input - Efficiency up to 97% - Internal pensation, Inrush Current Limiting, and Internal Soft Start - Small External ponents - Protection Features Include OVP, SCP, and - Small QFN-12 (2mmx2mm) Package APPLICATIONS - Two-Cell and Three-Cell Alkaline, Ni Cd or Ni MH, or Single-Cell Li Battery Consumer Products - Personal Medical Devices - Portable Media Players - Wireless Peripherals - Gaming Accessories All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
