1 / 21 page MP2166 6V, Dual 2A/2A or 3A/1A, Low Quiescent Current, Synchronous Buck with PG and SS MP2166 Rev. 1.0 www.MonolithicPower.com 1 3/14/2017 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2017 MPS. All Rights Reserved. DESCRIPTION The MP2166 is an internally compensated, dual, PWM, synchronous, step-down regulator that operates from a 2.7V to 6V input and generates an output voltage as low as 0.6V. The MP2166 can be configured as a 2A/2A or 3A/1A output current regulator and is ideal for powering portable equipment that runs on a single-cell lithium-ion (Li+) battery due to a low 60µA quiescent current. The MP2166 integrates dual, 55 mΩ, high-side switches and 20mΩ synchronous rectifiers for high efficiency without an external Schottky diode. The MP2166 has peak-current-mode control and internal compensation and is capable of low dropout configurations. Both channels can operate at 100% duty cycle. Full protection features include cycle-by-cycle current limit and thermal shutdown. The MP2166 requires a minimum number of readily available, standard, external components and is available in QFN-18 (2mmx3mm) and QFN-18 (2.5mmx3.5mm) packages. FEATURES 2.7V to 6V Operating Input Range 2A/2A or 3A/1A Continuous Current 55mΩ/20mΩ R DS(ON) Programmed Frequency up to 3MHz External Sync Clock Up to 3MHz 180o Phase Shifted Operation PG Indicators External SS and Track Adjustable Advanced Asynchronous Mode (AAM) or Forced Continuous Conduction Mode (CCM) Peak Efficiency >90% Output Adjustable from 0.6V to VIN 100% Duty Cycle Operation 60µA Quiescent Current Cycle-by-Cycle Over-Current Protection (OCP) Short-Circuit Protection (SCP) with Hiccup Mode and Valley Current Detection Thermal Shutdown Available in QFN-18 (2mmx3mm) and QFN- 18 (2.5mmx3.5mm) Packages APPLICATIONS Small/Handheld Devices DVD Drivers Smartphones and Feature Phones Battery-Powered Devices Portable Instruments All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
