General Description

The MCP16311/2 is a compact, high-efficiency, fixed

frequency, synchronous step-down DC-DC converter in

an 8-pin MSOP, or 2 x 3 mm TDFN package that

operates from input voltage sources up to 30V.

Integrated features include a high-side and a low-side

switch, fixed frequency peak current mode control,

internal compensation, peak current limit and

overtemperature protection. The MCP16311/2 provides

all the active functions for local DC-DC conversion, with

fast transient response and accurate regulation.

High converter efficiency is achieved by integrating the

current-limited, low-resistance, high-speed high-side

and low-side switches and associated drive circuitry.

The MCP16311 is capable of running in PWM/PFM

mode. It switches in PFM mode for light load

conditions and for large buck conversion ratios. This

results in a higher efficiency over all load ranges. The

MCP16312 runs in PWM-only mode, and is

recommended for noise-sensitive applications.

The MCP16311/2 can supply up to 1A of continuous

current while regulating the output voltage from 2V to

12V. An integrated, high-performance peak current

mode architecture keeps the output voltage tightly

regulated, even during input voltage steps and output

current 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 are

consumed from the input.

Output voltage is set with an external resistor divider.

The MCP16311/2 is offered in small MSOP-8 and

2 x 3 mm TDFN surface mount packages.
