1 / 18 page MP1605 2A, Synchronous, Step-Down Converter with Low 11 µA Quiescent Current in SOT563 Package MP1605 Rev. 1.0 www.MonolithicPower.com 1 6/17/2016 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2016 MPS. All Rights Reserved. DESCRIPTION The MP1605 is a monolithic, step-down, switch- mode converter with built-in, internal power MOSFETs. It achieves 2A of output current from a 2.3V to 5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. The constant-on-time control scheme provides a fast transient response and eases loop stabilization. Full protection features include cycle-by-cycle current limiting and thermal shutdown. The MP1605 is available in an ultra-small SOT563 package and requires a minimal number of readily available, standard, external components. The MP1605 is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems. FEATURES Low I Q: 11μA 2.2MHz Switching Frequency EN for Power Sequencing Wide 2.3V to 5.5V Operating Input Range Output Adjustable from 0.6V Up to 2A Output Current 120mΩ and 80mΩ Internal Power MOSFET Switches Output Discharge Short-Circuit Protection (SCP) with Hiccup Mode Stable with Low ESR Output Ceramic Capacitors Available in a SOT563 Package 100% Duty Cycle APPLICATIONS Wireless/Networking Cards Portable and Mobile Devices Battery-Powered Devices Low-Voltage I/O System Power Solid-State Drives (SSDs) All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
