3.General Description
The MCP16311/2 is a compact, high-efficiency, fixedfrequency, synchronous step-down DC-DC converter inan 8-pin MSOP, or 2 x 3 mm TDFN package thatoperates from input voltage sources up to 30V.Integrated features include a high-side and a low-sideswitch, fixed frequency peak current mode control,internal compensation, peak current limit andovertemperature protection. The MCP16311/2 providesall the active functions for local DC-DC conversion, withfast transient response and accurate regulation.High converter efficiency is achieved by integrating thecurrent-limited, low-resistance, high-speed high-sideand low-side switches and associated drive circuitry.The MCP16311 is capable of running in PWM/PFMmode. It switches in PFM mode for light loadconditions and for large buck conversion ratios. Thisresults in a higher efficiency over all load ranges. TheMCP16312 runs in PWM-only mode, and isrecommended for noise-sensitive applications.The MCP16311/2 can supply up to 1Aof continuouscurrent while regulating the output voltage from 2V to12V. An integrated, high-performance peak currentmode architecture keeps the output voltage tightlyregulated, even during input voltage steps and outputcurrent transient conditions common in power systems.The EN input is used to turn the device on and off.While off, only a few micro amps of current areconsumed from the input.Output voltage is set with an external resistor divider.The MCP16311/2 is offered in small MSOP-8 and2 x 3 mm TDFN surface mount packages.
